haha no that doesnt...but thats cool ^_^

anonymous · Answer

The denominators are the same, so set the numerators equal.

anonymous · Answer

However, because there is (x-4) in the denominator, x=4 will cause division by zero.

hero · Answer

$$\frac{x}{x-4} = \frac{4}{x-4}$$

$$\frac{x}{x-4} - \frac{4}{x-4} = 0$$

$$\frac{x-4}{x-4}= 0$$
$$1 = 0$$
