\frac{4}{0.01}+\frac{-6x}{0.01}-6.5=\frac{0.02-2x}{0.02}-7.5
Divide each term of 4-6x by 0.01 to get \frac{4}{0.01}+\frac{-6x}{0.01}.
400+\frac{-6x}{0.01}-6.5=\frac{0.02-2x}{0.02}-7.5
Expand \frac{4}{0.01} by multiplying both numerator and the denominator by 100. Anything divided by one gives itself.
400-600x-6.5=\frac{0.02-2x}{0.02}-7.5
Divide -6x by 0.01 to get -600x.
393.5-600x=\frac{0.02-2x}{0.02}-7.5
Subtract 6.5 from 400 to get 393.5.
393.5-600x=\frac{0.02}{0.02}+\frac{-2x}{0.02}-7.5
Divide each term of 0.02-2x by 0.02 to get \frac{0.02}{0.02}+\frac{-2x}{0.02}.
393.5-600x=1+\frac{-2x}{0.02}-7.5
Divide 0.02 by 0.02 to get 1.
393.5-600x=1-100x-7.5
Divide -2x by 0.02 to get -100x.
393.5-600x=-6.5-100x
Subtract 7.5 from 1 to get -6.5.
393.5-600x+100x=-6.5
Add 100x to both sides.
393.5-500x=-6.5
Combine -600x and 100x to get -500x.
-500x=-6.5-393.5
Subtract 393.5 from both sides.
-500x=-400
Subtract 393.5 from -6.5 to get -400.
x=\frac{-400}{-500}
Divide both sides by -500.
x=\frac{4}{5}
Reduce the fraction \frac{-400}{-500} to lowest terms by extracting and canceling out -100.
