    x = 4 OR x = - 4

    Step-by-step explanation:

    To find the solution, you can set both equations equal to one another:

    (1) y=2x+1; (2) y=x^2+2x-15

    2x+1 = x^2+2x-15

    Then solve for the x-values that make this true.

    2x+1 = x^2+2x-15

    1 = x^2 - 15

    16 = x^2

    x = 4 OR x = - 4
