Explicație pas cu pas:
[tex]\frac{2x + 1}{3} = \frac{x - 3}{6} - \frac{x + 3}{4} + \frac{2x + 1}{12} \\ [/tex]
[tex]4(2x + 1) = 2(x - 3) - 3(x + 3) + 2x + 1 \\ [/tex]
[tex]8x + 4 = 2x - 6 - 3x - 9 + 2x + 1[/tex]
[tex]8x + 4 = x - 14[/tex]
[tex]8x - x = - 14 - 4[/tex]
[tex]7x = - 18[/tex]
[tex]\implies x = - \frac{18}{7} \\ [/tex]
