2x+1=\frac{2}{3}\times 4
Multiply both sides by 4.
2x+1=\frac{2\times 4}{3}
Express \frac{2}{3}\times 4 as a single fraction.
2x+1=\frac{8}{3}
Multiply 2 and 4 to get 8.
2x=\frac{8}{3}-1
Subtract 1 from both sides.
2x=\frac{8}{3}-\frac{3}{3}
Convert 1 to fraction \frac{3}{3}.
2x=\frac{8-3}{3}
Since \frac{8}{3} and \frac{3}{3} have the same denominator, subtract them by subtracting their numerators.
2x=\frac{5}{3}
Subtract 3 from 8 to get 5.
x=\frac{\frac{5}{3}}{2}
Divide both sides by 2.
x=\frac{5}{3\times 2}
Express \frac{\frac{5}{3}}{2} as a single fraction.
x=\frac{5}{6}
Multiply 3 and 2 to get 6.
