Answer:


x<(16)/(125)

Explanation:

First we will multiply everything by 10 to get rid of the decimals.


4.2x*10+5.6*10<7.2*10-8.3x*10\\42x+56<72-83x

Subtract 56 from both sides:


42x+56-56<72-83x-56\\42x<-83x+16

Add 83x to both sides:


42x+83x<-83x+16+83x\\125x<16

Divide both sides by 125:


(125x)/(125)<(16)/(125)\\x<(16)/(125)
