С ПРОВЕРКОЙ

1)

[tex] - 6x - 5x = - 6 - 12[/tex]

[tex] - 11x = - 18[/tex]

[tex]x = \frac{18}{11} = 1 \frac{7}{11} [/tex]

2)

[tex] - 3x = - 0.5 + 4[/tex]

[tex] - 3x = 3.5[/tex]

[tex]x = - \frac{35}{30} = - 1 \frac{1}{6} [/tex]

3)

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

[tex] - x - x - 2x = 3 - 1[/tex]

[tex] - 4x = 2[/tex]

[tex]x = - 0.5[/tex]

4)

[tex] - 3x - 3 + 4x - 4 = - 6x - 6[/tex]

[tex] - 3x + 4x + 6x = 3 + 4 - 6[/tex]

[tex]7x = 1[/tex]

[tex]x = \frac{1}{7} [/tex]
