3\times \frac{4x+0.8}{0.6}-3\times \frac{0.03x+0.04}{0.03}=x-1
Multiply both sides of the equation by 3.
3\left(\frac{4x}{0.6}+\frac{0.8}{0.6}\right)-3\times \frac{0.03x+0.04}{0.03}=x-1
Divide each term of 4x+0.8 by 0.6 to get \frac{4x}{0.6}+\frac{0.8}{0.6}.
3\left(\frac{20}{3}x+\frac{0.8}{0.6}\right)-3\times \frac{0.03x+0.04}{0.03}=x-1
Divide 4x by 0.6 to get \frac{20}{3}x.
3\left(\frac{20}{3}x+\frac{8}{6}\right)-3\times \frac{0.03x+0.04}{0.03}=x-1
Expand \frac{0.8}{0.6} by multiplying both numerator and the denominator by 10.
3\left(\frac{20}{3}x+\frac{4}{3}\right)-3\times \frac{0.03x+0.04}{0.03}=x-1
Reduce the fraction \frac{8}{6} to lowest terms by extracting and canceling out 2.
20x+3\times \frac{4}{3}-3\times \frac{0.03x+0.04}{0.03}=x-1
Use the distributive property to multiply 3 by \frac{20}{3}x+\frac{4}{3}.
20x+4-3\times \frac{0.03x+0.04}{0.03}=x-1
Cancel out 3 and 3.
20x+4-3\left(\frac{0.03x}{0.03}+\frac{0.04}{0.03}\right)=x-1
Divide each term of 0.03x+0.04 by 0.03 to get \frac{0.03x}{0.03}+\frac{0.04}{0.03}.
20x+4-3\left(x+\frac{0.04}{0.03}\right)=x-1
Cancel out 0.03 and 0.03.
20x+4-3\left(x+\frac{4}{3}\right)=x-1
Expand \frac{0.04}{0.03} by multiplying both numerator and the denominator by 100.
20x+4-3x-3\times \frac{4}{3}=x-1
Use the distributive property to multiply -3 by x+\frac{4}{3}.
20x+4-3x-4=x-1
Multiply -3 times \frac{4}{3}.
17x+4-4=x-1
Combine 20x and -3x to get 17x.
17x=x-1
Subtract 4 from 4 to get 0.
17x-x=-1
Subtract x from both sides.
16x=-1
Combine 17x and -x to get 16x.
x=\frac{-1}{16}
Divide both sides by 16.
x=-\frac{1}{16}
Fraction \frac{-1}{16} can be rewritten as -\frac{1}{16} by extracting the negative sign.
