0.3x=0.18x+18
Use the distributive property to multiply 0.18 by x+100.
0.3x-0.18x=18
Subtract 0.18x from both sides.
0.12x=18
Combine 0.3x and -0.18x to get 0.12x.
x=\frac{18}{0.12}
Divide both sides by 0.12.
x=\frac{1800}{12}
Expand \frac{18}{0.12} by multiplying both numerator and the denominator by 100.
x=150
Divide 1800 by 12 to get 150.
