You are going to want to take -4y and put it to the other side: X-4y=19 Which is: x=4y+19 6x+y=4 Now substitute x ! 6(4y+19)+y=4 Distribute it 24y+114+y=4 Now combine like terms 25y+114=4 Subtract 114 both sides 25y= -110 Y=-4.4
Now you have y so take either equation and substitute the y X-4(1.4)=19 X+17.6=19 X=1.4 Y=-4.4
