1. Problem Description

We need to solve the equation 2xx4=4+8x4\frac{2x}{x-4} = 4 + \frac{8}{x-4}.

2. Solution Steps

First, we multiply both sides of the equation by (x4)(x-4) to eliminate the fractions.
(x4)2xx4=(x4)(4+8x4)(x-4) \cdot \frac{2x}{x-4} = (x-4) \cdot (4 + \frac{8}{x-4})
2x=4(x4)+82x = 4(x-4) + 8
2x=4x16+82x = 4x - 16 + 8
2x=4x82x = 4x - 8
Next, subtract 4x4x from both sides.
2x4x=4x84x2x - 4x = 4x - 8 - 4x
2x=8-2x = -8
Now, divide both sides by 2-2.
2x2=82\frac{-2x}{-2} = \frac{-8}{-2}
x=4x = 4
However, we must check if x=4x=4 is a valid solution because it makes the denominator x4x-4 equal to zero. If x=4x=4, the original equation becomes
2(4)44=4+844\frac{2(4)}{4-4} = 4 + \frac{8}{4-4}
80=4+80\frac{8}{0} = 4 + \frac{8}{0}
Since division by zero is undefined, x=4x=4 is not a solution. Therefore, there is no solution.
