c=3t-15
Use the distributive property to multiply 3 by t-5.
3t-15=c
Swap sides so that all variable terms are on the left hand side.
3t=c+15
Add 15 to both sides.
\frac{3t}{3}=\frac{c+15}{3}
Divide both sides by 3.
t=\frac{c+15}{3}
Dividing by 3 undoes the multiplication by 3.
t=\frac{c}{3}+5
Divide c+15 by 3.
c=3t-15
Use the distributive property to multiply 3 by t-5.
