[tex] \frac{x + 3}{2} + \frac{2x - 1}{3} = \frac{x}{6} \: | \times 6[/tex]

[tex] \frac{6(x + 3)}{2} + \frac{6(2x - 1)}{3} = \frac{6x}{6} [/tex]

[tex]3(x + 3) + 2(2x - 1) = x[/tex]

[tex]3x + 9 + 4x - 2 = x[/tex]

[tex]3x + 4x - x = - 9 + 2[/tex]

[tex]6x = - 7[/tex]

[tex]x = - \frac{7}{6} [/tex]
