    Both the lines shown by above two equations have same slope = 3 i. e. the lines are parallel to each other i. e. they don't intersect each other hence the given system of linear equations has no solution.

    x = - 1; y = 1

    Step-by-step explanation:

    3x - y = - 4

    x + y = 0

    Since you have - y and + y in the two equations, you can add them and eliminate y.

    Add the equations.

    4x = - 4

    x = - 1

    Now substitute - 1 for x in the second equation and solve for y.

    -1 + y = 0

    y = 1
