-1.1x>-5.5 divide both sides by -1.1......remember....we have to "reverse" the inequality sign when we divide by a negative...
x < 5
So, in interval notation, we have
(- ∞ , 5)
----------------------------------------------------------------------------------------------------
10(1/5x+4)<10(1/5x-3) divide both sides by 10
(1/5x+4)<(1/5x-3) subtract 1/5x from both sides
4 < -3 this is impossible......no solution exists !!!
