  1. 2x+y=6….(1)
    6x+3y=20……(2)

    Isolate y from equation (1) and find the value of x and y.
    2x+y=6
    or y=62x

    x y
    0 6
    1 4
    3 0

    Similarly, isolate x from equation (2) and find the values of x and y.
    6x+3y=20
    or x=(203y)/6

    x y
    10/3 0
    7/3 2
    4/3 4

    Graph:
    From the graph, both the lines are parallel.
    Therefore this system has no solution.
