To determine which system of linear equations appears to have a solution of (3, 0), we need to look for a description where the two lines intersect at the point (3, 0).
Among the options you provided, the third one states: "On a coordinate plane, 2 lines intersect at (3, 0)."
This point of intersection indicates that the solution to the system of linear equations is indeed (3, 0).
Therefore, the correct answer is: On a coordinate plane, 2 lines intersect at (3, 0).
