(-y+4)+ (9y-6) (9y-y) + (4-6) 8y - 2
Y=4 because 4+2=6
4
3y+6=y-2We want to get all the y-terms on one sides and everything else on the other.To do this we subtract y from both sides.3y+6-y=y-2-y Adding like terms gives us (2y+6=-2)Next, we subtract 6 from both sides.[2y+6-6=(-2)-6] Adding like terms gives us [2y=-8] So y=(-4)To double check plug y=(-4) into the beginning equations and see if they are equal.3(-4)+6=(-6)(-4)-2=(-6)They are both equal so Y=(-4) is the correct answer
So -3x - 6 = x - 4, ie -2 = 4x so x = -½ and y = -4½
