4 |x = 5| = 20
First, divide both sides by 4. / Your problem should look like: \(|x + 5| = 5\)
Second, simplify \(\frac{20}{4}\) to 5. / Your problem should look like: \(|x + 5| = 5\)
Third, break the problem into 2 equations. / x + 5 = 5 and -(x + 5) = 5
Fourth, solve x + 5 = 5. /
Cancel 5 on both sides. / \(x = 0\)
Fifth, solve -(x + 5) = 5 /
Simplify brackets / \(-x - 5 = 5\)
Add 5 to both sides / \(-x = 5 + 5\)
Add 5 + 5 / \(-x = 10\)
Multiply both sides by -1 / \(x = -10\)
x = -10
Sixth, collect the solutions to the problems. / Your problem should look like: \(x = -10, 0\)
Answer: x = -10, 0
