Simplifying 12(x + 20) = 372

Reorder the terms:
12(20 + x) = 372
(20 * 12 + x * 12) = 372
(240 + 12x) = 372
 
Solving 240 + 12x = 372
 
Solving for variable 'x'.
 
Move all terms containing x to the left, all other terms to the right.
 
Add '-240' to each side of the equation.
240 + -240 + 12x = 372 + -240
 
Combine like terms:
240 + -240 = 0
0 + 12x = 372 + -240
12x = 372 + -240

Combine like terms: 372 + -240 = 132
12x = 132

Divide each side by '12'.
x = 11

12(x+20)=372
12x+240=372
12x=132
x=11
