Question

mn if m+n =8 and m-n=2​

Answer 1

Answer:let mark the equation m+n=8 as......1 & mark the equation m-n=2 as.....2..

On adding equation 1 and 2,we get,

m+n+m-n=8+2

2m=10

m=5

On putting the value of m in equation 1 we get,

5+n=8

n=3

now mn = 5*3=8...

finish

Step-by-step explanation:

Answer 2

Answer:

the answers is m=5,n=3

Step-by-step explanation:

by. adding both equation we get m+m+n-n=8+2

2m=10

so m =5

putting m=5in one of the above given two equation we get n=2
