3=3\left(x-2\right)
Variable x cannot be equal to 2 since division by zero is not defined. Multiply both sides of the equation by x-2.
3=3x-6
Use the distributive property to multiply 3 by x-2.
3x-6=3
Swap sides so that all variable terms are on the left hand side.
3x=3+6
Add 6 to both sides.
3x=9
Add 3 and 6 to get 9.
x=\frac{9}{3}
Divide both sides by 3.
x=3
Divide 9 by 3 to get 3.
