Answer:

x = 6

Step-by-step explanation:

In algebra, the goal is always to isolate the variable, so its value can be determined.

Step 1: Simplify

9x - 12 = 5x + 12

Step 2: Subtract 5x

To solve, we want all the variables on one side, so remove 5x from both sides.

4x - 12 = 12

Step 3: Add 12

4x = 24

Step 4: Divide by 4

x = 6

Step 5: Check

9(6) - 12 = 7(6) - 2(6) + 12

42 = 42 ✔

Step 6: Answer

x = 6

I'm always happy to help :)
