4 |x = 5| = 20
First, divide both sides by 4. / Your problem should look like:
Second, simplify

to 5. / Your problem should look like:
Third, break the problem into 2 equations. / x + 5 = 5 and -(x + 5) = 5
Fourth, solve x + 5 = 5. /
Cancel 5 on both sides. /
Fifth, solve -(x + 5) = 5 /
Simplify brackets /

Add 5 to both sides /

Add 5 + 5 /

Multiply both sides by -1 /

x = -10
Sixth, collect the solutions to the problems. / Your problem should look like:

Answer:
x = -10, 0
