Answer:
in Step 2, the student added 4 on the right and subtracted 4 on the left
Step-by-step explanation:
In Step 2, the student subtracted 4 on the left side of the equation, but incorrectly added 4 on the right. (The same operation needs to be performed on both sides of the equation.) The correct step 2 would be ...
-8x = -32 . . . . correct step 2
x = 4 . . . . . correct step 3
Let's solve your equation step-by-step.
x+6(x−1)=7(3+x)
Step 1: Simplify both sides of the equation.
x+6(x−1)=7(3+x)
x+(6)(x)+(6)(−1)=(7)(3)+(7)(x)(Distribute)
x+6x+−6=21+7x
(x+6x)+(−6)=7x+21(Combine Like Terms)
7x+−6=7x+21
7x−6=7x+21
Step 2: Subtract 7x from both sides.
7x−6−7x=7x+21−7x
−6=21
Step 3: Add 6 to both sides.
−6+6=21+6
0=27
