\frac{120}{0.04}+\frac{-10x}{0.04}=\frac{54+10x}{0.06}
Divide each term of 120-10x by 0.04 to get \frac{120}{0.04}+\frac{-10x}{0.04}.
\frac{12000}{4}+\frac{-10x}{0.04}=\frac{54+10x}{0.06}
Expand \frac{120}{0.04} by multiplying both numerator and the denominator by 100.
3000+\frac{-10x}{0.04}=\frac{54+10x}{0.06}
Divide 12000 by 4 to get 3000.
3000-250x=\frac{54+10x}{0.06}
Divide -10x by 0.04 to get -250x.
3000-250x=\frac{54}{0.06}+\frac{10x}{0.06}
Divide each term of 54+10x by 0.06 to get \frac{54}{0.06}+\frac{10x}{0.06}.
3000-250x=\frac{5400}{6}+\frac{10x}{0.06}
Expand \frac{54}{0.06} by multiplying both numerator and the denominator by 100.
3000-250x=900+\frac{10x}{0.06}
Divide 5400 by 6 to get 900.
3000-250x=900+\frac{500}{3}x
Divide 10x by 0.06 to get \frac{500}{3}x.
3000-250x-\frac{500}{3}x=900
Subtract \frac{500}{3}x from both sides.
3000-\frac{1250}{3}x=900
Combine -250x and -\frac{500}{3}x to get -\frac{1250}{3}x.
-\frac{1250}{3}x=900-3000
Subtract 3000 from both sides.
-\frac{1250}{3}x=-2100
Subtract 3000 from 900 to get -2100.
x=\frac{-2100}{-\frac{1250}{3}}
Divide both sides by -\frac{1250}{3}.
