Question

The minimum and maximum temperature for a day in Cupcake Town can be modeled by the equation below:

3|x − 8| + 15 = 18

What are the minimum and maximum temperatures for this day?

x = 1, x = 17

x = −7, x = 9

x = 7 x = 9

No solution @leon88 @DarkBlueChocobo

Answer 1

First subtract 15 from both sides, you get 3/x-8/ = 3

Now divide both sides by 3, you get
/x-8/ = 1

Now set x - 8 = 1 and x - 8 = -1

So, x = 9 and x = 7

Seems like the minimum is 7 and maximum is 9.
