    Exclamation Quadratic functions - (simutaneous)

    Can someone show me the steps to solve this question???

    1) Solve for the pronumerals ALGEBRAICALLY:

    y= x^2 - 3x -2
    y= 2x + 4

    b) By sketching the graphs of these equations show how the simultaneous solution can be obtained?

    Can you solve this?
