\frac{1}{4}x+C=4y
Swap sides so that all variable terms are on the left hand side.
C=4y-\frac{1}{4}x
Subtract \frac{1}{4}x from both sides.
\frac{1}{4}x+C=4y
Swap sides so that all variable terms are on the left hand side.
\frac{1}{4}x=4y-C
Subtract C from both sides.
\frac{\frac{1}{4}x}{\frac{1}{4}}=\frac{4y-C}{\frac{1}{4}}
Multiply both sides by 4.
x=\frac{4y-C}{\frac{1}{4}}
Dividing by \frac{1}{4} undoes the multiplication by \frac{1}{4}.
x=16y-4C
Divide 4y-C by \frac{1}{4} by multiplying 4y-C by the reciprocal of \frac{1}{4}.
