What are the values of y if the double inequality holds 15

What are the values of y if the double inequality holds?

15 < 5y-30=<25

Solution

We\'ll start by solving the left side inequality:

15 < 5y-30

We\'ll divide by 5 both sides:

3 < y - 6

We\'ll add 6 both sides:

3+6 < y

y > 9

We\'ll solve the right side inequality:

5y-30=<25

We\'ll divide by 5 both sides:

y - 6 =< 5

We\'ll add 6 both sides:

y =< 6 + 5

y =< 11

The interval of possible values for y is: [9 , 11].
