    Answer:

    x > -2

    Step-by-step explanation:

    First, you simplify both sides of the inequality by combining like terms

    -8x + 2x -16 < -5x + 7x

    -6x - 16 < 2x

    Then, you add 6x to both sides in order to isolate x (bring all the Xs to one side)

    -6x - 16 + 6x < 2x + 6x

    -16 < 8x

    Lastly, you divide by 8 in order to cancel out 8x solve for x. Since 8 is not a negative number, you DO NOT flip the sign.

    \frac{-16}{8} < \frac{8x}{8}

    -2 < x
