Solving for variable 'x'.

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

Add '-0.1x' to each side of the equation.
3.6 + 0.05x + -0.1x = 1.8 + 0.1x + -0.1x

Combine like terms: 0.05x + -0.1x = -0.05x
3.6 + -0.05x = 1.8 + 0.1x + -0.1x

Combine like terms: 0.1x + -0.1x = 0.0
3.6 + -0.05x = 1.8 + 0.0
3.6 + -0.05x = 1.8

Add '-3.6' to each side of the equation.
3.6 + -3.6 + -0.05x = 1.8 + -3.6

Combine like terms: 3.6 + -3.6 = 0.0
0.0 + -0.05x = 1.8 + -3.6
-0.05x = 1.8 + -3.6

Combine like terms: 1.8 + -3.6 = -1.8
-0.05x = -1.8

Divide each side by '-0.05'.
x = 36

Simplifying
x = 36
