5\times 2x-15x=x-18
Multiply both sides of the equation by 15, the least common multiple of 3,15,5.
10x-15x=x-18
Multiply 5 and 2 to get 10.
-5x=x-18
Combine 10x and -15x to get -5x.
-5x-x=-18
Subtract x from both sides.
-6x=-18
Combine -5x and -x to get -6x.
x=\frac{-18}{-6}
Divide both sides by -6.
x=3
Divide -18 by -6 to get 3.
