These are linear equations so their graphs are straight lines. The easiest way to draw them is to identify for each equation where the line cuts across the axes. The cut on the y axis is given by setting x=0 in each equation, on the x axis it's where y=0. Take the first equation. When x=0 y=11, so mark this point on the y axis. When y=0 x=-11/3 (-3 2/3) so mark this point on the x axis. Join them by extending the line beyond the points of intercept. Take the other equation and do the same. The intercepts are (0,15/2) and (-6,0). Where the lines cross is the solution. The lines intersect at (-2,5). The equations can also be solved by substitution or as simultaneous equations. So x=-2 and y=5 is the solution.
