Answer:

B) 2

Explanation:

Step 1: Plug in the values of n and p.


  • m(4) + 6 = m + 3(4)

  • 4m + 6 = m + 12

Step 2: Subtract m from both sides.


  • 4m + 6 - m = m + 12 - m

  • 3m+6=12

Step 3: Subtract 6 from both sides.


  • 3m + 6 - 6 = 12 - 6

  • 3m = 6

Step 4: Divide both sides by 3.


  • (3m)/(3) = (6)/(3)

  • m = 2

Step 5: Check if solution is correct.


  • (2)(4)+(6)=(2)+3(4)

  • 8 + 6 = 2 + 12

  • 14 = 14

Therefore, the answer is B) 2.
