Best ResponseYou've already chosen the best response.1Not so. Multiplying both sides by 12 gives us: \[\large \frac{12(x4)}{4}+\frac{12x}{3}=72\]

Best ResponseYou've already chosen the best response.2if you are sure that "x>0" you can multiply by "x" but in this case we can not be sure about x>0 if you do it by multiply ,some part of answer is lost !

Best ResponseYou've already chosen the best response.2\[first \space suppose \space x>0 \\\frac{5x+1}{x}<0 \rightarrow 5x+1<x \\4x<1\\x<\frac{1}{4}\\ now\\x>o ,x<\frac{1}{4} \] for the second part note that sign will change \[x<0 \\\frac{5x+1}{x}<1 \\mutilply \space by x\\5x+1>x\\4x>1\\x>\frac{1}{4}\\now\\x>\frac{1}{4} ,x<0 \rightarrow \frac{1}{4}<x<0\]
