Answer:

infinitely many solutions

Explanation:


m+7=3+m+4

Combine like terms


m+7=7+m

Rearrange variables to the left side of the equation


m-m=7-7

Apply the Inverse Property of Addition


m-m=7-7\\ 0=0

Bases on the given conditions, the (system of) equation(s) has


infinitely\ many\ solutions

I hope this helps you

Infinite solutions.

If you set up the equation, m+7=3+m+4,
first add the 3 and 4 together to get: m+7=m+7. There you can see that they equal each other but you could go on and subtract m from both sides and then you have 7=7 which would also tell you it’s infinite solutions.
