Answer: x = 3

              x = 2 is restricted (aka extraneous)

Step-by-step explanation:

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

[tex]\frac{x}{x - 1}[/tex] - [tex]\frac{1}{x - 2}[/tex] = [tex]\frac{2x - 5}{(x - 1)(x - 2)}[/tex]

RESTRICTIONS: x - 1 ≠ 0  → x ≠ 1 and x - 2 ≠ 0  →  x ≠ 2 (because the denominator cannot equal zero)

[tex]\frac{x}{x - 1}(x - 1)(x - 2)[/tex] - [tex]\frac{1}{x - 2}(x - 1)(x - 2)[/tex] = [tex]\frac{2x - 5}{(x - 1)(x - 2)}(x - 1)(x - 2)[/tex]

x(x - 2) - 1(x - 1) = 2x - 5

x² - 2x - x + 1 = 2x - 5

x² - 3x + 1 = 2x - 5

    -2x  +5   -2x  +5

x² - 5x + 6 = 0

(x - 2)(x - 3) = 0

x - 2 = 0         x - 3 = 0

  +2  +2          +3  +3

x      = 2          x      = 3     These are the solutions, but x = 2 is restricted
