Answer: x = -7, 1
Step-by-step explanation:
1) Add 1 on both sides of the equation
- | x + 3 | = -4
2) Divide both sides by -1.
| x + 3 | = 4
3) Because the left side of the equation is an absolute value, you have to split the equation.
Equation #1:
x + 3 = 4
x = 1
Equation #2:
x + 3 = -4
x = -7
x = -7, 1
