Step-by-step explanation:
[tex]$\frac{y}{3}-\frac{3}{4}>\frac{1}{2}\\[/tex]
We can see that the LCM of the denominators is 12, so, by multiplying the whole equation by 12, we can cancel out all of the fractions.
[tex]$\frac{y}{3}(12)-\frac{3}{4}(12)>\frac{1}{2}(12)[/tex]
[tex]4y-9>6[/tex]
[tex]4y>15[/tex]
[tex]y>\frac{15}{4}[/tex]
