The solution is (4, 1).

m = 4

n = 1

Step-by-step explanation:

m + n = 5

m - n = 3

m + n + m - n = 5 + 3

m + m = 5 + 3

2m = 5 + 3

2m = 8

2m ÷ 2 = 8 ÷ 2

m = 4

m + n = 5

m - n = 3

4 + n = 5

4 - 4 + n = 5 - 4

n = 1

4 - n = 3

4 - n = 3

4 - 4 - n = 3 - 4

- n = - 1

- n · - 1  = - 1 · - 1

n = 1

the answer
