Question

The steps below show the incomplete solution to find the value of m for the equation 4m − 2m + 4 = −1 + 13:

Answer 1

The second 2m=8
2m=12-4

Answer 2

Answer:

B) 2m = 8

Step-by-step explanation:

4m − 2m + 4 = −1 + 13

Here we have to solve for "m"

The given steps are:

Step 1: 4m − 2m + 4 = −1 + 13

Step 2: 4m − 2m + 4 = 12

Step 3: 2m + 4 = 12

The next step would be subtract 4 from both sides,

Step 4: 2m + 4 - 4 = 12 - 4

2m = 8

Therefore, the answer is B) 2m = 8
