8=3x-\left(1\times 3+1\right)
Multiply both sides of the equation by 3.
8=3x-\left(3+1\right)
Multiply 1 and 3 to get 3.
8=3x-4
Add 3 and 1 to get 4.
3x-4=8
Swap sides so that all variable terms are on the left hand side.
3x=8+4
Add 4 to both sides.
3x=12
Add 8 and 4 to get 12.
x=\frac{12}{3}
Divide both sides by 3.
x=4
Divide 12 by 3 to get 4.
