z=10+5t+15
Use the distributive property to multiply 5 by t+3.
z=25+5t
Add 10 and 15 to get 25.
25+5t=z
Swap sides so that all variable terms are on the left hand side.
5t=z-25
Subtract 25 from both sides.
\frac{5t}{5}=\frac{z-25}{5}
Divide both sides by 5.
t=\frac{z-25}{5}
Dividing by 5 undoes the multiplication by 5.
t=\frac{z}{5}-5
Divide z-25 by 5.
z=10+5t+15
Use the distributive property to multiply 5 by t+3.
z=25+5t
Add 10 and 15 to get 25.
