### Help Solving Algebra Problems

Also, note that if we divide each member of the equation by 3, we obtain the equations whose solution is also 4. Sometimes one method is better than another, and in some cases, the symmetric property of equality is also helpful. However, the solutions of most equations are not immediately evident by inspection.

Thus, in the equation x 3 7, the left-hand member is x 3 and the right-hand member is 7. Notice that x 3 7 and x 4 are equivalent equations since the solution is the same for both, namely 4. In solving equations, we use the above property to produce equivalent equations in which the variable has a coefficient of 1.

In this chapter, we will develop certain techniques that help solve problems stated in words. Notice in the equation 3x 3 x 13, the solution 5 is not evident by inspection but in the equation x 5, the solution 5 is evident by inspection. If we first add -1 to (or subtract 1 from) each member, we get the solution of the original equation is the number -3 however, the answer is often displayed in the form of the equation x -3.

Equations such as x 3 7 are first-degree equations, since the variable has an exponent of 1. The solutions to many such equations can be determined by inspection. If both members of an equation are multiplied by the same nonzero quantity, the resulting equation is equivalent to the original equation.

If the same quantity is added to or subtracted from both membersof an equation, the resulting equation is equivalent to the originalequation. We can determine whether or not a given number is a solution of a given equation by substituting the number in place of the variable and determining the truth or falsity of the result. Solution we may solve for t in terms of r and d by dividing both members by r to yield in the above example, we solved for t by applying the division property to generate an equivalent equation.

The terms to the left of an equals sign make up the left-hand member of the equation those to the right make up the right-hand member. In solving any equation, we transform a given equation whose solution may not be obvious to an equivalent equation whose solution is easily noted. In solving equations, we use the above property to produce equivalent equations that are free of fractions. Although we can see by inspection that the solution is 9, because -(9) -9, we can avoid the negative coefficient by adding -2x and 9 to each member of equation (1). Any one or more of the following steps listed on page 102 may be appropriate.

Equations that involve variables for the measures of two or more physical quantities are called formulas. Enter an equation along with the variable you wish to solve it for and click the solve button. Solution we substitute the value 3 for x in the equation and see if the left-hand member equals the right-hand member. If both members of an equation are multiplied by the same nonzero quantity, the resulting equation is equivalent to the original equation. The value of the variable for which the equation is true (4 in this example) is called the solution of the equation.

In the next example, we simplify above the fraction bar before applying the properties that we have been studying. In this case, we get from which the solution 9 is obvious. This property states this enables us to interchange the members of an equation whenever we please without having to be concerned with any changes of sign. In the next example, we use the addition-subtraction property and the division property to solve an equation. We can solve for any one of the variables in a formula if the values of the other variables are known.

In the above example, we can check the solution by substituting - 3 for x in the original equation the symmetric property of equality is also helpful in the solution of equations. Using the addition or subtraction property, write the equation with all terms containing the unknown in one member and all terms not containing the unknown in the other. These techniques involve rewriting problems in the form of symbols. The first-degree equations that we consider in this chapter have at most one solution. Sometimes one method is better than another, and in some cases, the symmetric property of equality is also helpful. In this chapter, we will develop certain techniques that help solve problems stated in words. Any one or more of the following steps listed on page 102 may be appropriate. Solution we may solve for t in terms of r and d by dividing both members by r to yield in the above example, we solved for t by applying the division property to generate an equivalent equation. .
