Whats the step by step process to solve 3 (*-9) = 30

3 (x-9) = 30

3 (x-9) + 9=30+9

3x/3=39/3

x=39/3

x=13

You have to show a new line for each operation when the directions call for step by step.

step 1 : 3 • (x - 9) - 30 = 0 Step 2 : Step 3 : Pulling out like terms:

3.1 Pull out like factors:

3x - 57 = 3 • (x - 19)

Equation at the end of step 3 : 3 • (x - 19) = 0 Step 4 : Equations which are never true:

4.1 Solve : 3 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

4.2 Solve : x-19 = 0

Add 19 to both sides of the equation:

x = 19

One solution was found : x = 19
