Best ResponseYou've already chosen the best response.1\[\frac25 x  9 < \frac9{10}\]First You want to isolate the monomial with x, so:\[\implies \frac25 x<\frac9{10}+9\] follow so far?

Best ResponseYou've already chosen the best response.1\[9+ \frac9{10}= {99\over10}\]\[\therefore \frac25 x<{99 \over 10}\] Next you want to get rid of the coefficient of x...

Best ResponseYou've already chosen the best response.1You do that by multiplying both sides by 5/2... Note that when multiplying both sides by a negative number flips the < sign to >\[\frac52 \cdot\frac25\cdot x>\frac52\cdot {99 \over 10}\]\[\implies 1\cdot x>{99 \over 4}\]\[\implies x>24{3 \over 4}\]
