2x+\frac{1}{2}=2\times \frac{4}{3}
Multiply both sides by \frac{4}{3}, the reciprocal of \frac{3}{4}.
2x+\frac{1}{2}=\frac{2\times 4}{3}
Express 2\times \frac{4}{3} as a single fraction.
2x+\frac{1}{2}=\frac{8}{3}
Multiply 2 and 4 to get 8.
2x=\frac{8}{3}-\frac{1}{2}
Subtract \frac{1}{2} from both sides.
2x=\frac{16}{6}-\frac{3}{6}
Least common multiple of 3 and 2 is 6. Convert \frac{8}{3} and \frac{1}{2} to fractions with denominator 6.
2x=\frac{16-3}{6}
Since \frac{16}{6} and \frac{3}{6} have the same denominator, subtract them by subtracting their numerators.
2x=\frac{13}{6}
Subtract 3 from 16 to get 13.
x=\frac{\frac{13}{6}}{2}
Divide both sides by 2.
x=\frac{13}{6\times 2}
Express \frac{\frac{13}{6}}{2} as a single fraction.
x=\frac{13}{12}
Multiply 6 and 2 to get 12.
