{{ printedBook.courseTrack.name }} {{ printedBook.name }} Looking at the graph, we can tell that the lines intersect at $(4,2).$

Ron-Jon is correct that the $x$-value of the solution is equal to $4.$ However, this is not the correct way of stating the solution to a system of equations. It should be given as an ordered pair. Since the lines intersect at $(4,2),$ this is the solution. Thus, Lena-Jon is correct.
