    x-value is 4

    Step-by-step explanation:

    2x-3y=-1

    3x+4y=24

    We can solve the equation by eliminating y

    We multiply the first equation by 4 and the second by 3

    4 (2x-3y=-1)

    3 (3x+4y=24)

    8x - 12y = - 4

    9x + 12y = 72

    Then we add the two equations;

    8x - 12y = - 4

    9x + 12y = 72

    17x = 68

    x = 4

    Thus the x-value is 4
