Answer:
Last option; x = 1 or x = -5
Step-by-step explanation:
1. Simplify the equation.
Step 1: Add 7 to both sides.
Step 2: Divide both sides by 4.
2. Now that we simplified the equation to this, we have to solve for absolute value. We know either or
.
3. (Solving for 1st possibility)
Step 1: Subtract 4 from both sides.
Step 2: Divide both sides by 2.
4. (Solving for 2nd possibility)
Step 1: Subtract 4 from both sides.
Step 2: Divide both sides by 2.
5. Now that we have the outcomes of both of our possibilities as x = 1 or x = -5, the last option matches with what we got.
