Question

if n equals to 14-3m and m+2n equals to 13 find m and n​

Answer 1

Step-by-step explanation:

n = 14 - 3m

m + 2n = 13

m + 2(14 - 3m) = 13

m + 28 - 6m = 13

28 - 13 = 6m - m

5m = 15

m = 3

n = 14 - 3(3) = 14 - 9 = 5

Answer 2

According to question,

n=14-3m

m+2n=13

_________

3m+n=14.......×1

m+2n=13........×3

___________

3m+n=14

3m+6n=39

- - -

__________

-5n=-25

n=5

3m+n=14

3m+5=14

3m=9

m=3
