4) Solve for x using y = x - 4.
    x = y + 4 
    Now plug x in to y = 6x - 10.
    y = 6(y + 4) - 10
    y = 6y + 24 - 10
    y = 6y + 14
    -5y = 14
    y = -14/5
    Plug y back in to x = y + 4.
    x = -14/5 + 4
    x = 1.2
    (6/5, -14/5)

5) Make the expressions equal to each other.
    2x + 3 = 3x - 6
    9 = x
    x = 9
