Step-by-step explanation:

Pull out like factors:

3x - 15 = 3 • (x - 5)

Equation at the end of step 1:

Step 2:

Equations which are never true:

2.1 Solve : 3 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2 Solve : x-5 = 0

Add 5 to both sides of the equation:

x = 5

One solution was found:

x = 5

My answer is 9 because 3x-3=12
