54=-\frac{1}{2}y+3
Combine \frac{1}{2}y and -y to get -\frac{1}{2}y.
-\frac{1}{2}y+3=54
Swap sides so that all variable terms are on the left hand side.
-\frac{1}{2}y=54-3
Subtract 3 from both sides.
-\frac{1}{2}y=51
Subtract 3 from 54 to get 51.
y=51\left(-2\right)
Multiply both sides by -2, the reciprocal of -\frac{1}{2}.
y=-102
Multiply 51 and -2 to get -102.
