Punctul g)
[tex]x + \frac{5}{3} = - \frac{1}{2} \implies 6x + 10 = - 3 \\ 6x = - 13\implies \tt x = - \frac{13}{6} [/tex]
Punctul h)
[tex]x + \frac{2}{3} = - \frac{ 4}{3}\implies 3x + 2 = - 4 \\ 3x = - 6\implies\tt x = - 2[/tex]
Punctul i)
[tex] |3x + 5| = 7 \implies 3x + 5 = \pm7 \\ 3x + 5 = - 7 \ \ \ \ sau \ \ \ \ 3x + 5 = 7 \\ 3x = - 12 \ \ \ \ \ sau \ \ \ \ \ 3x = 2 \\ \tt x _ 1= - 4 \ \ \ \ \ sau \ \ \ \ \ x _2 = \frac{2}{3} [/tex]
Punctul j)
[tex] \frac{3x}{5} - \frac{2x}{3} = - \frac{1}{3} \\ 9x - 10x = - 5 \\ - x = - 5 \implies\tt x = 5[/tex]
Punctul k)
[tex]\small2x + 7 = - 11\implies 2x = - 18\implies\tt x = - 9 \\ [/tex]
Punctul l)
[tex]6(x + 5) - 3x = 21 \\ 6x + 30 - 3x = 21 \\ 3x = - 9\implies \tt x = - 3[/tex]
Punctul m)
[tex] \frac{7x}{6} - 1 \frac{1}{2} = \frac{x + 3}{3} \\ \frac{7x}{6} - \frac{3}{2} = \frac{x + 3}{3} \\ 7x - 9 = 2x + 6 \\ 7x - 2x = 6 + 9 \\ 5x = 15 \implies\tt x = 3[/tex]
