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
