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

when n = 2; m = 2

when m=5;   n =

Step-by-step 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

2n - 5(5) = -10

2n - 25 = -10

    +25     +25

2n = 15

2        2

   n =
