Помогите пожалуйста.

1
$\left \{ {{3x-2 \geq x+1} \atop {4-2x \leq x-2}} \right. \ \ \to \ \ \left \{ {{3x-x \geq 1+2} \atop {-2x -x\leq -2-4}} \ \ \to \ \ \left \{ {{2x \geq 3} \atop {-3x\leq -6}}\ \ \to \ \ \left \{ {{x \geq 1.5 } \atop {x \geq 2}}$
$x\in[2; +\infty)$

2
$\left \{ {{3x\ \textgreater \ 12+11x} \atop {5x-1 \geq 0}} \right. \ \ \to \ \ \left \{ {{3x-11x\ \textgreater \ 12} \atop {5x \geq 1}} \right. \ \ \to \ \ \left \{ {{-8x\ \textgreater \ 12} \atop {x \geq 0.2}} \right. \ \ \to \ \ \left \{ {{x\ \textless \ -1.5} \atop {x \geq 0.2}} \right. \\ \\ x\in \O$
