Use the substitution method to solve the system. {m+n=5m−n=3 what is the solution? the solution is (4, 1). there is no solution. there are an infinite number of solutions. the solution is (2, −1).

The value of m and n is 4 and 1. The solution is (4,1). Option A is correct.

The given system of equations is,

It is required to solve the equations using the substitution method.

So, use the first equation to get the value of n and substitute it in the second equation as,

Therefore, the value of m and n is 4 and 1. The solution is (4,1). Option A is correct.
