Plot the points D (2,1), E (0, 2) and F (4, 0) on the same graph paper. Join D, E and -F and extend it c-on both sides to obtain the graph of the equation 3x+6y =12
we find that the lines represented by equations 2x + 4y = 10 and 3x + 6y = 12 are parallel. So, the two lines have no common point. Hence, the given system of equations has no solution.
