Since the equation has absolute value, that means that answer can be either positive or negative.
Split the original equation into two equations.
x + 5 = 3 and x + 5 = -3
Now, solve for x in both equations.
Solution #1:
x + 5 = 3
~Subtract 5 to both sides
x + 5 - 5 = 3 - 5
~Simplify
x = -2
Solution #2:
x + 5 = -3
~Subtract 5 to both sides
x + 5 - 5 = -3 - 5
~Simplify
x = -8
Best of Luck!
