Thanks a lot Just this one question im lost on.
Plz eplain with words and number!
THANKSSSSSS

4x-y=-11
-y=-11-4x (divide all of them by -1 so there's no negative)
Y= 11-4x
6x+2y=-2
6x+2(11+4x)=-2
6x+ 22 + 8x= -2
14x +22-22 =-2-22
14x= -22 (divide my 14)
X= -22/14
X= 11/7

3(4x-y=-11)
-2(6x+2y=-2)
12x-3y=-33
-12x-4y= 4
-7y= -29 (divide by -7)
Y= -29/-7
Y= 29/7
