Question:
Make the given changes in the indicated examples of this section and then solve the resulting problems.
In Example 3, change 12 to −12 in each of the four illustrations and then solve.
Data from Example 3
In each of the following equations, we may isolate x, and thereby solve the equation, by performing the indicated operation.
Transcribed Image Text:
x3 = 12 add 3 to both sides x 3 + 3 = 12 + 3 x = 15 x + 3 = 12 subtract 3 from both sides x + 3-3 = 12 - 3 x = 9 نرا || 12 3 multiply both sides by 3 = 3(12) x = 36 3x = 12 divide both sides by 3 3x 12 3 3 x = 4 =
