Question

How do you solve `- 5| x + 1| = -10`?

Answer 1

You may start by dividing both sides by `-5`

Explanation:

`->|x+1|=2`

In fact this represents two equations, depending on the value of `x` being smaller or greater than `-1`

`x>=-1: x+1=2->x=1`

`x<=-1:-(x+1)=2->-x-1=2->x=-3`
graph{|x+1| [-10, 10, -5, 5]}
