<u><em>w(h) represents how many hours per week </em></u>

How to solve |3+x| -5 = -3
Irina-Kira [14]
To solve for x, you first add 5 to both sides so it remains equal.

3 + x = 2

Then you simply subtract 3 on both sides.

x = -1

Substitute your solution into the equation and see it is true.

|3+(-1)) - 5 = -3

The equation is true, therefore your answer is: x = -1
