3x-2y=0 doesn't have an "answer." It's the equation of a straight line. You need to specify what you're looking for. For example, are you hoping to find the slope of this line? or the x- and y-intercepts? Or a point on the line?
Rearranging 3x-2y=0, 2y=3x, and so y = (3/2)x. The slope of this line is (3/2).
If you want the y-intercept, let x=0 and solve for y. Result: y=0.
If you want x-int let y=0 and solve for x. Result: (0,0).
The graph passes through the origin (0,0).
Starting at the origin, move 2 spaces to the right and then 3 spaces up.
Put a dot at this intersection. Draw a line thrugh (0,0) and (2,3).
