Answer 2

Given:

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

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

To Find:

The value of m and n.

Solution:

Subtract eq.(i) from eq.(ii), we get

5n = 20

or, n = 20/5

or, n = 4 ... (iii)

4m - 2(4) = -4 (from eq.iii)

or, 4m = -4 + 8

or, m = 4/4

or, m = 1

Answer:

The value of m and n is 1 and 4 respectively.

Option 4. ( 1, 4 ) is the correct answer.
