3x + 2(x - 9) = 8x + x - 14
Simplify.
3x + 2x - 18 = 8x + x - 14
Add like terms.
5x - 18 = 9x - 14
Now, we need to add 18 to both sides, and then subtract 9x from both sides so that all variables are on the left side of the equation, and all other numbers are on the right.
5x - 9x = -14 + 18
Simplify.
-4x = 4
Divide both sides by -4.
x = -1
