Question

M + n is 4 and 3m + 2n is 16, find the value of m & n?

Answer 1

Answer:

given :-

M+n = 4

M = 4- n - equation 1

3M + 2n =16

using equation 1

3(4-n) +2n =16

12 - 3n + 2n = 16

12 -n =16

-n = 16 - 12

n = -4

putting n in equation 1 :-

M = 4 - n

M = 4 - (-4)

M = 4+4

M = 8

therefore :-

M =8 and n = -4

Answer 2

Step-by-step explanation:

m

$m + n = 4 \\m = 4 - n \\ 3m + 2n = 16 \\ 4 - n + 2n = 16 \\ n = 12 \\ m = - 8$
