3.2x+\frac{1}{2}+0.8x=\frac{5}{6}
Add 0.8x to both sides.
4x+\frac{1}{2}=\frac{5}{6}
Combine 3.2x and 0.8x to get 4x.
4x=\frac{5}{6}-\frac{1}{2}
Subtract \frac{1}{2} from both sides.
4x=\frac{5}{6}-\frac{3}{6}
Least common multiple of 6 and 2 is 6. Convert \frac{5}{6} and \frac{1}{2} to fractions with denominator 6.
4x=\frac{5-3}{6}
Since \frac{5}{6} and \frac{3}{6} have the same denominator, subtract them by subtracting their numerators.
4x=\frac{2}{6}
Subtract 3 from 5 to get 2.
4x=\frac{1}{3}
Reduce the fraction \frac{2}{6} to lowest terms by extracting and canceling out 2.
x=\frac{\frac{1}{3}}{4}
Divide both sides by 4.
x=\frac{1}{3\times 4}
Express \frac{\frac{1}{3}}{4} as a single fraction.
x=\frac{1}{12}
Multiply 3 and 4 to get 12.
