By definition:
4y-2 = 6y+8
4y-6y = 8+2
-2y = 10
y = -5 and by substituting this value into the equation x = -22

3x-6y=-8
7y-8 = 6y+1 7y-6y = 1+8 y = 9
Subtracting gives: 10x = 80 so x = 8 and y = 5
Two ways to see this: 6y=8-9+6y 6y=6y-1 No answer here 6y= 8-(9+6y) 6y+(9+6y)=8 12y+9=8 12y=-1 y= -(1/12) or -0.08333...
