y = -5, x = 3

  • anonymous
thanks a lot. :D

here is how i did this: I wanted to get x or y by itsself so i turned 5x - 7y = 50 into 5x= 7y + 50
anonymous
  • anonymous
then, i divided by 5
anonymous
  • anonymous
and got x = 7/5y + 10
anonymous
  • anonymous
then i just plugged that whole thing into the x variable in the first equation like this -11(7/5y + 10) - 10y = 17, then you distribute the -11 and add together the two y terms and put the constant on the other side and get y by itsself. After that you can just plug y into either equation to get x
