    Step-by-step explanation:

    The system of equations can be solved using elimination to eliminate one variable and solve for the other. Given the two equations:

    3x + 4y = 17 and - 4x - 3y = - 18, we need to have opposite coefficients to eliminate a variable. Multiplying the first equation by '3' and the second by '4':

    3 (3x + 4y = 17) = 9x + 12y = 51

    4 (-4x - 3y = - 18) = - 16x - 12y = - 72

    -7x = - 21

    x = 3

    Solve for y: 3 (3) + 4y = 17 or 9 + 4y = 17

    y = 2
