Answer 7

Let's solve your equation step-by-step.
5(|2x−2|)+8=18
Step 1: Add -8 to both sides.
5(|2x−2|)+8+−8=18+−8
5(|2x−2|)=10
Step 2: Divide both sides by 5.
5(|2x−2|)5=105
|2x−2|=2
Step 3: Solve Absolute Value.
|2x−2|=2
We know either 2x−2=2 or 2x−2=−2
2x−2=2(Possibility 1)
2x−2+2=2+2(Add 2 to both sides)
2x=4
2x2=42(Divide both sides by 2)
x=2
2x−2=−2(Possibility 2)
2x−2+2=−2+2(Add 2 to both sides)
2x=0
2x2=02(Divide both sides by 2)
x=0
Answer:
x=2 or x=0
