See a solution process below:

#### Explanation:

MUltiply each side of thee equation by $\textcolor{red}{3}$ to solve for $y$ while keeping the equation balanced:

$\textcolor{red}{3} \times \frac{7}{2} = \textcolor{red}{3} \times \frac{y}{3}$

$\frac{21}{2} = \cancel{\textcolor{red}{3}} \times \frac{y}{\textcolor{red}{\cancel{\textcolor{b l a c k}{3}}}}$

$\frac{21}{2} = y$

$y = \frac{21}{2}$
