1)
[tex] \frac{1}{x - 1} = \frac{10}{3} [/tex]
[tex]3 = 10(x - 1)[/tex]
[tex]3 = 10x - 10[/tex]
[tex] - 10x = - 10 - 3[/tex]
[tex] - 10x = - 13[/tex]
[tex]x = \frac{13}{10} [/tex]
2)
[tex] \frac{x + 2}{x} = 0.25[/tex]
[tex]x + 2 = 0.25x[/tex]
[tex]x - 0.25x = - 2[/tex]
[tex]0.75x = - 2[/tex]
[tex]x = - \frac{8}{3} [/tex]
