-2+\frac{1}{2}I=Q
Swap sides so that all variable terms are on the left hand side.
\frac{1}{2}I=Q+2
Add 2 to both sides.
\frac{\frac{1}{2}I}{\frac{1}{2}}=\frac{Q+2}{\frac{1}{2}}
Multiply both sides by 2.
I=\frac{Q+2}{\frac{1}{2}}
Dividing by \frac{1}{2} undoes the multiplication by \frac{1}{2}.
I=2Q+4
Divide Q+2 by \frac{1}{2} by multiplying Q+2 by the reciprocal of \frac{1}{2}.
