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?

Best ResponseYou've already chosen the best response.0hears all the steps Let's solve your equation stepbystep. x−2+3=7 Step 1: Add 3 to both sides. x−2+3+−3=7+−3 x−2=4 Step 2: Solve Absolute Value. x−2=4 We know either x−2=4 or x−2=−4 x−2=4(Possibility 1) x−2+2=4+2(Add 2 to both sides) x=6 x−2=−4(Possibility 2) x−2+2=−4+2(Add 2 to both sides) x=−2 Answer: x=6 or x=−2
