Question

The steps below show the incomplete solution to find the value of x for the equation

7x + 8 − 3x = −6 + 10:

Step 1: 7x + 8 − 3x = −6 + 10
Step 2: 7x + 8 − 3x = 4
Step 3: 4x + 8 = 4

Which of these is most likely the next step?

A. 4x = −12

B. 4x = −4

C. 4x = 4

D. 4x = 12

Answer 1

The next step would be B. Then you divide both sides of the equation by the same term, which would be putting 4 on the denominators. Finally you simplify and get x=-1
