2x-1=\frac{5}{2}\times 3
Multiply both sides by 3.
2x-1=\frac{5\times 3}{2}
Express \frac{5}{2}\times 3 as a single fraction.
2x-1=\frac{15}{2}
Multiply 5 and 3 to get 15.
2x=\frac{15}{2}+1
Add 1 to both sides.
2x=\frac{15}{2}+\frac{2}{2}
Convert 1 to fraction \frac{2}{2}.
2x=\frac{15+2}{2}
Since \frac{15}{2} and \frac{2}{2} have the same denominator, add them by adding their numerators.
2x=\frac{17}{2}
Add 15 and 2 to get 17.
x=\frac{\frac{17}{2}}{2}
Divide both sides by 2.
x=\frac{17}{2\times 2}
Express \frac{\frac{17}{2}}{2} as a single fraction.
x=\frac{17}{4}
Multiply 2 and 2 to get 4.
