Answer:

Step-by-step explanation:

Answer 2

Answer:

m = 1

n = 4

Step-by-step explanation:

4m - 2n = -4.......(i)

4m + 3n = 16......(ii)

We will subtract (i) and (ii)

4m - 2n = -4

- 4m ± 3n = ± 16

=> -5n = -20

=> n = -20 ÷ (-5)

=> n = 4

Now put the value of n in equation (i)

4m - 2n = -4

=> 4m - 2(4) = -4

=> 4m - 8 = -4

=> 4m = -4+8

=> 4m = 4

=> m = 4/4

=> m = 1

Hence the value of m and n is 1 and 4 respectively.

hope it helps.
