i KNOW THAT I HAVE TO ADD EQUATION 2 AND THREE TO GET THE FOLLOWING
IN ORDER TO GET
THEN I DON'T KNOW FROM HERE
There a couple ways to solve this. You have
x+y = 1
You could first show
x=1-y and z=y+3 and substitute them into the 3rd equation to get
2(1-y)+3y+y+3=1 and solve for y to get
5+2y=1 so 2y=-4 and y=-2
then put this into the first two equations to solve for x and z.
