Answer:

t=-p/5+20

Explanation:

p=100−5t

Swap sides so that all variable terms are on the left hand side.

100−5t=p

Subtract 100 from both sides.

−5t=p−100

Divide both sides by −5.

−5t/5 = p - 100/-5

Dividing by −5 undoes the multiplication by −5.

t = p - 100/-5

Divide p−100 by −5.

t=-p/5+20
