Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1.2x' to each side of the equation.
12 + -1.2x = -1.2 + 1.2x + -1.2x

Combine like terms: 1.2x + -1.2x = 0.0
12 + -1.2x = -1.2 + 0.0
12 + -1.2x = -1.2

Add '-12' to each side of the equation.
12 + -12 + -1.2x = -1.2 + -12

Combine like terms: 12 + -12 = 0
0 + -1.2x = -1.2 + -12
-1.2x = -1.2 + -12

Combine like terms: -1.2 + -12 = -13.2
-1.2x = -13.2

Divide each side by '-1.2'.
x = 11

Simplifying
x = 11
