5x+0.8-3x=0
Subtract 3x from both sides.
2x+0.8=0
Combine 5x and -3x to get 2x.
2x=-0.8
Subtract 0.8 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-0.8}{2}
Divide both sides by 2.
x=\frac{-8}{20}
Expand \frac{-0.8}{2} by multiplying both numerator and the denominator by 10.
x=-\frac{2}{5}
Reduce the fraction \frac{-8}{20} to lowest terms by extracting and canceling out 4.
