Question

|x+5| = 8, what is the absolute value function?

Answer 1

x=3

x=-13

Explanation:

With these type of equations, there will always be two answers because x can be positive or negative. So, there are two equations.

x+5=8

x+5=-8

Simplify both of them

x=3

x=-13

We know these are correct because if you plug them into the original equation |x+5|=8, both are good solutions
