Simplifying
9x + -2 = 27

Reorder the terms:
-2 + 9x = 27

Solving
-2 + 9x = 27

Solving for variable 'x'.

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

Add '2' to each side of the equation.
-2 + 2 + 9x = 27 + 2

Combine like terms: -2 + 2 = 0
0 + 9x = 27 + 2
9x = 27 + 2

Combine like terms: 27 + 2 = 29
9x = 29

Divide each side by '9'.
x = 3.222222222

Simplifying
x = 3.222222222
