0.04x+7-0.07x=6.73
Use the distributive property to multiply 0.07 by 100-x.
-0.03x+7=6.73
Combine 0.04x and -0.07x to get -0.03x.
-0.03x=6.73-7
Subtract 7 from both sides.
-0.03x=-0.27
Subtract 7 from 6.73 to get -0.27.
x=\frac{-0.27}{-0.03}
Divide both sides by -0.03.
x=\frac{-27}{-3}
Expand \frac{-0.27}{-0.03} by multiplying both numerator and the denominator by 100.
x=9
Divide -27 by -3 to get 9.
