    1) expand the brackets

    6 (-3 - x) - 2x = 14

    -18 - 6x - 2x = 14

    simplify

    -18 - 8x = 14

    then add 18 to both sides to get the x's on there own

    -8x = 32

    then divide by - 8

    x = 32/-8

    x = - 4

    2) multiply everything by 7x

    2 + (6 x 7x) + (17x * 7x) = 18 x 7x

    2 + 42x + 119x^2 = 126x

    put everything on one side

    119x^2 - 84x + 2 = 0

    then use quadratic equation to solve

    x = 0.024671849 or 0.6812105039
