Question

67. If mn + p = m + 3n, what is the value of m when

Answer 1

Answer:

2

Step-by-step explanation:

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

Answer 2

Answer:

B) 2

Step-by-step 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.

• $\frac{3m}{3} = \frac{6}{3}$
• $m = 2$

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.
