Explicación paso a paso:

hola °

A)

[tex]2 - x = x - 8[/tex]

[tex] - x - x = - 8 - 2[/tex]

[tex] - 2x = - 10[/tex]

[tex]x = \frac{ - 10}{ - 2} [/tex]

[tex]x = 5[/tex]

B)

[tex]2x - 1 = 5x + 8[/tex]

[tex]2x - 5x = 8 + 1[/tex]

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

[tex]x = \frac{9}{ - 3} [/tex]

[tex]x = - 3[/tex]

C)

[tex]2(1 + 2x) = 10[/tex]

[tex]2 + 4x = 10[/tex]

[tex]4x = 10 - 2[/tex]

[tex]4x = 8[/tex]

[tex]x = \frac{8}{4} [/tex]

[tex]x = 2[/tex]
