3x-x-1.5x=15
Multiply both sides of the equation by 3.
2x-1.5x=15
Combine 3x and -x to get 2x.
0.5x=15
Combine 2x and -1.5x to get 0.5x.
x=\frac{15}{0.5}
Divide both sides by 0.5.
x=\frac{150}{5}
Expand \frac{15}{0.5} by multiplying both numerator and the denominator by 10.
x=30
Divide 150 by 5 to get 30.
