Below are the steps to solve an equation:
Step 1: |x − 2| + 3 = 7
Step 2: |x − 2| = 7 − 3
Step 3: |x − 2| = 4
Which of the following is a correct next step to solve the equation?
x + 2 = −4
−x − 2 = 4
x + 2 = 4
x − 2 = −4
I thought it was B, but I got it wrong. Could some one please help me?

If I said that \(|x-y|\)=z, what are the two posibilities?
|x − 2| = 4
@Lyralei, there is more than 1 posibility for that

hears all the steps
Let's solve your equation step-by-step.
Step 1: Add -3 to both sides.
Step 2: Solve Absolute Value.
We know either x−2=4 or x−2=−4
x−2+2=4+2(Add 2 to both sides)
x−2+2=−4+2(Add 2 to both sides)
x=6 or x=−2
Okay, well that dosent work. Because I already know that x=-2
like @Ahsome said |x+y| = z have two answers
x+y =z or x+y =-z
