4x - (9 - 3x) = 8x - 1

If you would like to solve the equation 4 * x - (9 - 3 * x) = 8 * x - 1, you can calculate this using the following steps:

4 * x - (9 - 3 * x) = 8 * x - 1
4 * x - 9 + 3 * x = 8 * x - 1
4 * x + 3 * x - 8 * x = -1 + 9
-1 * x = 8    /(-1)
x = -8

The result you are looking for is -8.

Remove the parenthesis
4x - 9 + 3x = 8x - 1

Simplify like terms
7x - 9 = 8x - 1

Add 1 on both sides
7x - 8 = 8x

Subtract 7x on both sides
-8 = x

Your answer is x = -8
