ok. i have to solve this problem:
-x+4y=8
2x-3y=-16
i know that 1st you have to try to get "y" by itself on one of the sides but after that im confused. this is what i did...
-x+4y=8
+x +x
__________
4y=x+8
--- -----
4 4
y= ?? +2
then for the other side when i tried yto find "y" i did this...
2x-3y=-16
-2x -2x
-3y= -2x-16
----- --------
-3 -3
y= 2/3x+16/3
and for the 2nd one, when i plug it into the other problem it doesn't come out right. so what do i do??
