    Are you trying to figure out which side of the equation is greater than?

    If so this is how it comes out if I remember correctly from my previous MAT class.

    0.9x + 9 < 1.7x-8
    9.9x>-6.3

  • Math - ,

    0.9X + 9 <= 1.7X - 8.

    Add -1.7X AND -9 to both sides:
    0.9X - 1.7X <= -8 -9,
    Combine like-terms:
    -0.8X <= -17,
    Divide both sides by -0.8 and reverse inequality sign:
    X => 21.25.
