Solve, using the substitution method. m + n = 5

m – n = 3

There is no solution.

The solution is (2, –1)

The solution is (4, 1)

There are an infinite number of solutions.

Step-by-step explanation:

m-n = 3 becomes m=3+n

Substitute 3+n to m in m+n = 5

Therefore;

3+n+n = 5

3 + 2n = 5

2n = 2

n = 1

m - n = 3, n is 1

therefore;

m - 1 = 3

m = 4
