Question

. If 2n - 5m + 10 = 0, find
i) m, when n=2 ii) n, when m=5​

Answer 1

when n = 2; m = 2
`(4)/(5)`

when m=5; n =
`7(1)/(2)`

Explanation:

2n - 5m + 10 = 0

-10 -10

2n - 5m = -10

2(2) - 5m = -10

4 - 5m = -10

-4 -4

-5m = -14

-5 -5

m = 2
`(4)/(5)`

2n - 5(5) = -10

2n - 25 = -10

+25 +25

2n = 15

2 2

n =
`7(1)/(2)`
