2=2\left(x-3\right)
Subtract 1 from 3 to get 2.
2=2x-6
Use the distributive property to multiply 2 by x-3.
2x-6=2
Swap sides so that all variable terms are on the left hand side.
2x=2+6
Add 6 to both sides.
2x=8
Add 2 and 6 to get 8.
x=\frac{8}{2}
Divide both sides by 2.
x=4
Divide 8 by 2 to get 4.
