Exercice 1
[tex]2(x-1)+3(x+1)\ \textgreater \ 4(3x-2)\\\\2x-2+3x+3\ \textgreater \ 12x-8\\\\5x+1\ \textgreater \ 12x-8\\\\12x-8\ \textless \ 5x+1\\\\12x-5x\ \textless \ 1+8\\\\7x\ \textless \ 9\\\\\boxed{x\ \textless \ \dfrac{9}{7}}[/tex]
Exercice 2
[tex]\dfrac{3x-1}{4}\le\dfrac{5x+1}{6}\\\\\dfrac{3\times(3x-1)}{3\times4}\le\dfrac{2\times(5x+1)}{2\times6}\\\\\dfrac{3(3x-1)}{12}\le\dfrac{2(5x+1)}{12}\\\\3(3x-1)\le2(5x+1)\\\\9x-3\le10x+2\\\\10x+2\ge9x-3\\\\10x-9x\ge-3-2\\\\\boxed{x\ge-5}[/tex]
