Question

Plzzzz help meeeeeeeeeeeeeee

Answer 1

Explanation:

we have the set

`3m+4n = 2\\\\5m-4n = 14`

add them both

`(3m+4n)+(5m-4n) = 2+14\\\\(3m+5m)+(4n-4n) = 16\\\\8m=16\\\\m = (16)/(8)\\\\m = 2`

now plug in m = 2 in equation 1 (it could aso be equation 2)

`3m+4n = 2\\\\3(2)+4n = 2\\\\6+4n = 2\\\\4n = 2-6\\\\4n = -4\\\\n = -1`

so the solution is

m = 2

n = -1
