Exercise 60 Page 316

t=100

Practice makes perfect

To solve the equation, we have to isolate t on one side. Using the Multiplication Property of Equality, we will multiply both sides of the equation by 5. This will eliminate the denominator of the fraction and isolate t.

t/5=20

LHS * 5=RHS* 5

t/5* 5=20* 5

a/5* 5 = a

t=5* 20

t=100

To check that this solution is correct, substitute t=100 into the original equation and simplify.

t/5=20

t= 100

100/5 ? = 20

Calculate quotient

20 = 20 ✓

Since the left-hand side and right-hand side are equal, t=100 is the correct solution.
