Answer 2

Answer:

If 13m + 7n = 33; and, 7m + 13n = 27, then, the value of (m + n) will be 3.

Step-by-step explanation:

Given,

13m + 7n = 33 ...........(eq. 1)

7m + 13n = 27 ...........(eq. 2)

Now,

Adding eq. 1 and eq. 2, we get;

13m + 7n + 7m + 13n = 33 + 27

⇒ (13m + 7m) + (7n + 13n) = 60

⇒ 20m + 20n = 60

⇒ 20(m + n) = 60

⇒ (m + n) = 3
