To help you estimate the solution to a system of linear equations based on a graph, you'll need to provide the equations or a description of the graph itself. The solution to the system is typically found at the point where the lines represented by the equations intersect.
If you can describe the lines or equations, or share any relevant information about their slopes and y-intercepts, I can guide you through estimating the solution. Alternatively, if you can describe the intersection point you see on the graph, that would also help in providing an estimate!
