    If you re-arrange the two equation to make y the subject, it may be easier to plot.

    2x+ y = 5 \rightarrow y=5-2x
    x-2y=0 \rightarrow y=\frac{x}{2}

    Plot both lines and the point at which they intersect is the solution of the simultaneous equation.

    I'm not entirely certain, but I think you are asking for help with learning how to graph linear equations. If so, try here.
