Solving for variable 'x'.

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

Add '-0.05x' to each side of the equation.
-1.2 + 0.10x + -0.05x = -1 + 0.05x + -0.05x

Combine like terms: 0.10x + -0.05x = 0.05x
-1.2 + 0.05x = -1 + 0.05x + -0.05x

Combine like terms: 0.05x + -0.05x = 0.00
-1.2 + 0.05x = -1 + 0.00
-1.2 + 0.05x = -1

Add '1.2' to each side of the equation.
-1.2 + 1.2 + 0.05x = -1 + 1.2

Combine like terms: -1.2 + 1.2 = 0.0
0.0 + 0.05x = -1 + 1.2
0.05x = -1 + 1.2

Combine like terms: -1 + 1.2 = 0.2
0.05x = 0.2

Divide each side by '0.05'.
x = 4

Simplifying
x = 4
