Question 200516
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
