Question

|x − 11| = 5.

Here, x represents the measured temperature of the solution in degrees Fahrenheit.

Based on the above information, what is the temperature of the solution as measured by Robert?

Answer 1

Explanation:

the absolute value allows for 2 possible answers :

x - 11 = 5

and

x - 11 = -5

in both cases the absolute value delivers 5 as result.

x - 11 = 5

x = 16°F

x - 11 = -5

x = 6°F
