Answer:
B) 2
Explanation:
Step 1: Plug in the values of n and p.
Step 2: Subtract m from both sides.
Step 3: Subtract 6 from both sides.
Step 4: Divide both sides by 3.
Step 5: Check if solution is correct.
Therefore, the answer is B) 2.
2
mn + p = m + 3n, n = 4 and p = 6
m(4)+6=m+3(4)
4m+6=m+12
4m=m+6
3m=6
m=2
