\frac{3}{4}a=\frac{5}{6}x-\frac{2}{3}
Subtract \frac{2}{3} from both sides.
\frac{3}{4}a=\frac{5x}{6}-\frac{2}{3}
The equation is in standard form.
\frac{\frac{3}{4}a}{\frac{3}{4}}=\frac{\frac{5x}{6}-\frac{2}{3}}{\frac{3}{4}}
Divide both sides of the equation by \frac{3}{4}, which is the same as multiplying both sides by the reciprocal of the fraction.
a=\frac{\frac{5x}{6}-\frac{2}{3}}{\frac{3}{4}}
Dividing by \frac{3}{4} undoes the multiplication by \frac{3}{4}.
a=\frac{10x-8}{9}
Divide \frac{5x}{6}-\frac{2}{3} by \frac{3}{4} by multiplying \frac{5x}{6}-\frac{2}{3} by the reciprocal of \frac{3}{4}.
\frac{5}{6}x=\frac{3}{4}a+\frac{2}{3}
Swap sides so that all variable terms are on the left hand side.
\frac{5}{6}x=\frac{3a}{4}+\frac{2}{3}
The equation is in standard form.
\frac{\frac{5}{6}x}{\frac{5}{6}}=\frac{\frac{3a}{4}+\frac{2}{3}}{\frac{5}{6}}
Divide both sides of the equation by \frac{5}{6}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{\frac{3a}{4}+\frac{2}{3}}{\frac{5}{6}}
Dividing by \frac{5}{6} undoes the multiplication by \frac{5}{6}.
x=\frac{9a}{10}+\frac{4}{5}
Divide \frac{3a}{4}+\frac{2}{3} by \frac{5}{6} by multiplying \frac{3a}{4}+\frac{2}{3} by the reciprocal of \frac{5}{6}.
