8y+24=C
Use the distributive property to multiply 8 by y+3.
C=8y+24
Swap sides so that all variable terms are on the left hand side.
8y+24=C
Use the distributive property to multiply 8 by y+3.
8y=C-24
Subtract 24 from both sides.
\frac{8y}{8}=\frac{C-24}{8}
Divide both sides by 8.
y=\frac{C-24}{8}
Dividing by 8 undoes the multiplication by 8.
y=\frac{C}{8}-3
Divide C-24 by 8.
