I think that you should develope input output tables to make a graph or compare date.
so convert the equations to f(x)= or y=
2x+3y=3
3y=-2x+3
y=f(x)=(-2x+3)/3
substitute a number for x and solve
pick several different numbers for x
and develope an input output table
3x+3y=4
3y=-3x+4
y=f(x)=(-3x+4)/3
try it from here

You are given the equations for two lines. Usually you are asked to find the point that they have in common. Remember, lines can 1)intersect at one point 2) be parallel and not touch anywhere 3)be coindicdent and have every point in common
Let's solve this one using elimination

Subtract the two (it is easy this time since two of them have the same coefficient for the y term. Other times, you will have to do more math beforehand)
------------------

If x = 1, now solve for y

So the point these two lines intersect at is (1, 1/3)
