    If X-Y=3..how can you change this equation to show what Y equals?

    IF X -Y =3....then if we add Y to both sides we get X= 3 +Y.....now subtract 3 from both sides and what do you get?

    If you subtract 3 from both sides of x=3+y ????

    Now you know from the second equation that y = x-3....substitute x-3 for y in the first equation and solve for x.

    if y=x-3, then you could substitute. 4x+y=2 4x+(x-3)=2 ^ see what i did there? 5x-3=2 +3 +3 ------- 5x=5 /5 /5 ----- x=1

    then once you solved for x, you can plug that into one of the simpler equations and solve for y. Once you solve for both y and x, then you will have the points

    well let's see x-y=3 **plug in the value of x...x=1** 1-y=3 -1 -1 ------ -y=2 y=-2

    Maybe you might wanna follow @Jamierox4ev3r a little more,and maybe,just maybe you might get an idea of how to do it on your own. :)

    Does the substitution make sense @DJBreezy ? Just find the value of one variable, then substitute it into an equation
