Since I don't want to be lazy... here's the breakdown:

The second equation:
125/1000*x+y=875/1000*x
1/8*x+y=7/8*x
x+8y=7x
-6x+8y=0

So, the system looks like this:
x+y=140
-6x+8y=0

6x+6y=840
-6x+8y=0

=> 14y=840 => y=60

=> x=140-y=140-60=80

The second equation would look like this:
125/1000*x+y=875/1000*x
