Answer:

x = 20

Step-by-step explanation:

Starting equation: x - 36 + 12x = 224

Reorder: 12x + x (as there is no negative sign in front of the x) - 36 = 224

Add common terms: 13x - 36 = 224

Subtract (in this case add) common term to isolate variable: 13x + 36 = 224 + 36

Isolate variable by dividing both sides by 13: 13x = 260

Solve: x = 20
