{m+n=5
m−n=3

Use the substitution method.

The solution is (4, 1)(

There is no solution.

The solution is (2, −1)(2, −1).

There are an infinite number of solutions.

Respuesta :

simplify any of the equations:

m=3+n for example

then put the simplified equation into the other equation that is not simplified:

(3+n)+n=5

simplify:

3+2n=5
2n=2
n=1

plug into the first simplified equation for m:

m=3+n
m=3+1
m=4

answer:(1,4)

Answer:

the solution is (4,1)
