\frac{0.3x}{0.1}+\frac{-0.6}{0.1}=\frac{0.03x+0.02}{0.02}-1
Divide each term of 0.3x-0.6 by 0.1 to get \frac{0.3x}{0.1}+\frac{-0.6}{0.1}.
3x+\frac{-0.6}{0.1}=\frac{0.03x+0.02}{0.02}-1
Divide 0.3x by 0.1 to get 3x.
3x-6=\frac{0.03x+0.02}{0.02}-1
Expand \frac{-0.6}{0.1} by multiplying both numerator and the denominator by 10. Anything divided by one gives itself.
3x-6=\frac{0.03x}{0.02}+\frac{0.02}{0.02}-1
Divide each term of 0.03x+0.02 by 0.02 to get \frac{0.03x}{0.02}+\frac{0.02}{0.02}.
3x-6=1.5x+\frac{0.02}{0.02}-1
Divide 0.03x by 0.02 to get 1.5x.
3x-6=1.5x+1-1
Divide 0.02 by 0.02 to get 1.
3x-6=1.5x
Subtract 1 from 1 to get 0.
3x-6-1.5x=0
Subtract 1.5x from both sides.
1.5x-6=0
Combine 3x and -1.5x to get 1.5x.
1.5x=6
Add 6 to both sides. Anything plus zero gives itself.
x=\frac{6}{1.5}
Divide both sides by 1.5.
x=\frac{60}{15}
Expand \frac{6}{1.5} by multiplying both numerator and the denominator by 10.
x=4
Divide 60 by 15 to get 4.
