1) [latex]\frac{4x}{27}-x-\frac{3}{9}+x+\frac{1}{3}\ \textless \ 0[/latex]
[latex]\frac{4x}{27}-\frac{1}{3}+\frac{1}{3}\ \textless \ 0[/latex]
[latex]\frac{4x}{27}\ \textless \ 0[/latex]
[latex]27*\frac{4x}{27}\ \textless \ 27*0[/latex]
[latex]4x\ \textless \ 0[/latex]
[latex]x\ \textless \ 0[/latex]
2) [latex] \left \{ {{x-\frac{x}{4}\ \textgreater \ 2} \atop {3x-2\ \textgreater \ 4x-5.6}} \right. [/latex]
[latex] \left \{ {{4x-4*\frac{x}{4}\ \textgreater \ 4*2} \atop {3x-4x\ \textgreater \ -5.6+2}} \right. [/latex]
[latex] \left \{ {{4x-x\ \textgreater \ 8} \atop {-x\ \textgreater \ -3.6}} \right. [/latex]
[latex] \left \{ {{3x\ \textgreater \ 8} \atop {x\ \textless \ 3.6}} \right. [/latex]
[latex] \left \{ {{x\ \textgreater \ \frac{8}{3} } \atop {x\ \textless \ 3.6}} \right. [/latex]
