Either one will work. $y=\frac{7}{2}$

Work Step by Step

Distributing First $10=4y-4$ (Add 4 to each side) $14=4y$ (Divide each side by 4) $y=\frac{14}{4}$ (Simplify) $y=\frac{7}{2}$ Dividing First (Divide both sides by 4) $\frac{10}{4}=y-1$ (Simplify) $\frac{5}{2}=y-1$ (Add 1 to each side) $\frac{5}{2}+1=y$ $\frac{5}{2}+\frac{2}{2}=y$ $y=\frac{7}{2}$
