X+y= 1, -2x+4y=6 solve use substitute

Answers

X+y=1 Subtract y from both sides x=-y+1 Substitute into the other equation -2(-y+1)+4y=6 Divide by -2 -y+1+2y=3 Subtract 1 -y+2y=2 Add like terms Y=2 Substitute into first equation X+2=1 Subtract 2 from both sides X=-1 (-1,2) I hope this helps :) -2(-y+1)+4y=6 2y-2+4y=6 2y+4y=12 6y=12 Y=2 ^^Another way to do the substitution
