5x-30=3x\times \frac{1}{3}-2
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 3x, the least common multiple of 3x,3.
5x-30=x-2
Multiply 3 and \frac{1}{3} to get 1.
5x-30-x=-2
Subtract x from both sides.
4x-30=-2
Combine 5x and -x to get 4x.
4x=-2+30
Add 30 to both sides.
4x=28
Add -2 and 30 to get 28.
x=\frac{28}{4}
Divide both sides by 4.
x=7
Divide 28 by 4 to get 7.
