\frac{1}{2}y=25
Square both sides of the equation.
\frac{\frac{1}{2}y}{\frac{1}{2}}=\frac{25}{\frac{1}{2}}
Multiply both sides by 2.
y=\frac{25}{\frac{1}{2}}
Dividing by \frac{1}{2} undoes the multiplication by \frac{1}{2}.
y=50
Divide 25 by \frac{1}{2} by multiplying 25 by the reciprocal of \frac{1}{2}.
