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
