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
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.
