<span>9x + -4 = 77
Reorder the terms:
-4 + 9x = 77
Solving
-4 + 9x = 77
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 9x = 77 + 4
Combine like terms: -4 + 4 = 0
0 + 9x = 77 + 4
9x = 77 + 4
Combine like terms: 77 + 4 = 81
9x = 81
Divide each side by '9'.
x = 9
Simplifying
x = -9</span>
