    i) Solve he following equation by the quadratic formula :
    3X^2 + 4X -23 = 0

    ii) Find the values of x and y that satisfy the equations here given
    ( use the simultaneous equation method ) :
    3x + 2y = 22
    2x + 3y = 23

    iii) Solve graphically the following equations: show the graph as a part of the solution.

    iv) Using determinants solve the following equations :
    a) 2x+y = 3
    x+y = -2

    b) 4x + 2y -z = 9
    2x + y = 4
    x + 2y - 2z = 2
