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
