0.2x+225=375
Swap sides so that all variable terms are on the left hand side.
0.2x=375-225
Subtract 225 from both sides.
0.2x=150
Subtract 225 from 375 to get 150.
x=\frac{150}{0.2}
Divide both sides by 0.2.
x=\frac{1500}{2}
Expand \frac{150}{0.2} by multiplying both numerator and the denominator by 10.
x=750
Divide 1500 by 2 to get 750.
