e)

[tex] \frac{x}{2} - \frac{x}{3} = 2 \times 3[/tex]

[tex] \frac{x}{2} - \frac{x}{3} = 6[/tex]

[tex]3x - 2x = 36[/tex]

[tex]x = 36[/tex]

f)

[tex] - 3 \times (x + 1) = 2 \times (x + 6)[/tex]

[tex] - 3x - 3 = 2x + 12[/tex]

[tex] - 3x - 2x = 12 + 3[/tex]

[tex] - 5x = 15[/tex]

[tex]x = - 3[/tex]

g)

[tex] \frac{x - 1}{2} + \frac{3}{4} = \frac{x - 5}{6} + \frac{1}{12} [/tex]

[tex]6(x - 1) + 9 = 2(x - 5) + 1[/tex]

[tex]6x - 6 + 9 = 2x - 10 + 1[/tex]

[tex]6x + 3 = 2x - 9[/tex]

[tex]6x - 2x = - 9 - 3[/tex]

[tex]4x = - 12[/tex]

[tex]x = - 3[/tex]
