$\text{y + $\dfrac{1}{4}$ = 2 – $\dfrac{1}{2}$}$
$\text{y + $\dfrac{1}{4}$ = $\dfrac{4}{2}$ – $\dfrac{1}{2}$}$
$\text{y + $\dfrac{1}{4}$ = $\dfrac{4 – 1}{2}$}$
$\text{y + $\dfrac{1}{4}$ = $\dfrac{3}{2}$}$
$\text{y = $\dfrac{3}{2}$ – $\dfrac{1}{4}$}$
$\text{y = $\dfrac{6}{4}$ – $\dfrac{1}{4}$}$
$\text{y = $\dfrac{6 – 1}{4}$}$
$\text{y = $\dfrac{5}{4}$}$
$\textit{Ha1zzz}$
y + 1/4 = 2 – 1/2
y + 1/4 = 3/2
y = 3/2 – 1/4
y = 5/4
