Answer:
Infinite Solutions.
Step-by-step explanation:

Subtract m from both sides:



Both sides are equal.
This means that the value of m does not affect the end result of 7 = 7, which is true. Thus, there are infinite solutions as any value of m will still make the equation true.
2 + 65 + 7 × 3
= 2 + 65 + 21
= 67 + 21
= 88
answer is 88
