An equation is formed of two equal expressions. The correct option is B.
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The solution to the given equation can be done as,
m − 2m + 4 = −1 + 13
Step 1: 4m − 2m + 4 = −1 + 13
Step 2: 4m − 2m + 4 = 12
Step 3: 2m + 4 = 12
Step 4: 2m = 8
Step 5: m = 4
Hence, the step that is most likely to be the next step is 2m = 8.
