Question

solve the following simultaneous equation 7m-2n=40 ; m+n=10​

Answer 1

Answer:

Step-by-step explanation:

Eq:1=7m-2n=40

Eq:2=m+n=10

Now multiply 2 in eq 2

2m+2n=20

So by eliminating eq 1 and eq 2

2m+2n=20

7m-2n=40

_________

9m=60

m=60/9

m=20/3

Put the value of m in any eq and find the value of n.
