Question

if lyl = 5 what is the value of y

Answer 1

l5l=y is the answer to the problem

Answer 2

y = ± 5

The absolute value always returns a positive value

That is | - 5 | = | 5 | = 5

This is because it is a measure of how far the value is from the origin and both 5 and - 5 are 5 units from the origin.

Hence y = ± 5
