Solving for variable 'x'.

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

Add 'x' to each side of the equation.
3.6 + 8.1x + x = 3.7 + -1x + x

Combine like terms: 8.1x + x = 9.1x
3.6 + 9.1x = 3.7 + -1x + x

Combine like terms: -1x + x = 0
3.6 + 9.1x = 3.7 + 0
3.6 + 9.1x = 3.7

Add '-3.6' to each side of the equation.
3.6 + -3.6 + 9.1x = 3.7 + -3.6

Combine like terms: 3.6 + -3.6 = 0.0
0.0 + 9.1x = 3.7 + -3.6
9.1x = 3.7 + -3.6

Combine like terms: 3.7 + -3.6 = 0.1
9.1x = 0.1

Divide each side by '9.1'.
x = 0.01098901099

Simplifying
x = 0.01098901099
