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

Answer 1

Please have patience. Sometimes responses could take more than a few minutes.
4x-(9-3x)= 8x-1
Distribute
4x-9+3x=8x-1
Combine like terms
7x-9=8x-1
Get the variables (letters) on one side and numbers on the other..
Add 9 to both sides.
7x=8x+8
Subtract 8x from both sides.
-x=8
Divide both sides by -1.
x=-8

Answer 2

4x-(9-3x)= 8x-1
4x - 9 + 3x = 8x - 1
7x -8x = 9 - 1
x = -8
