3\left(2x-3x-3\right)+8=4x-\left(x+3\right)
Use the distributive property to multiply -3 by x+1.
3\left(-x-3\right)+8=4x-\left(x+3\right)
Combine 2x and -3x to get -x.
-3x-9+8=4x-\left(x+3\right)
Use the distributive property to multiply 3 by -x-3.
-3x-1=4x-\left(x+3\right)
Add -9 and 8 to get -1.
-3x-1=4x-x-3
To find the opposite of x+3, find the opposite of each term.
-3x-1=3x-3
Combine 4x and -x to get 3x.
-3x-1-3x=-3
Subtract 3x from both sides.
-6x-1=-3
Combine -3x and -3x to get -6x.
-6x=-3+1
Add 1 to both sides.
-6x=-2
Add -3 and 1 to get -2.
x=\frac{-2}{-6}
Divide both sides by -6.
x=\frac{1}{3}
Reduce the fraction \frac{-2}{-6} to lowest terms by extracting and canceling out -2.
