125=15x+\frac{40}{2}x
Multiply \frac{1}{2} and 40 to get \frac{40}{2}.
125=15x+20x
Divide 40 by 2 to get 20.
125=35x
Combine 15x and 20x to get 35x.
35x=125
Swap sides so that all variable terms are on the left hand side.
x=\frac{125}{35}
Divide both sides by 35.
x=\frac{25}{7}
Reduce the fraction \frac{125}{35} to lowest terms by extracting and canceling out 5.
