Solving
2x = -91.0 + 8x

Solving for variable 'x'.

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

Add '-8x' to each side of the equation.
2x + -8x = -91.0 + 8x + -8x

Combine like terms: 2x + -8x = -6x
-6x = -91.0 + 8x + -8x

Combine like terms: 8x + -8x = 0
-6x = -91.0 + 0
-6x = -91.0

Divide each side by '-6'.
x = 15.16666667

Simplifying
x = 15.16666667
