Answer

$x = 6$

Work Step by Step

1. Multiply by $x-5$ on both sides of the equation to obtain: $\frac{x}{x-5} - 4 = \frac{2}{x-5}$ $x - 4(x-5) = \frac{2(x-5)}{x-5}$ 2. Cancel out $x-5$ in the fraction to simplify: $x -4(x-5) = 2$ 3. Expand and solve for $x$: $x - 4x + 20 = 2$ $-3x + 20 -2 = 0$ $-3x + 18 = 0$ $-3(x - 6) = 0$ $x-6 = 0$ $x = 6$
