Sagot :

Let's solve the equation step-by-step to determine if it has any solutions:

The equation given is:

[tex]\[ \frac{x}{4x - 16} - 2 = \frac{1}{x - 4} \][/tex]

First, let's simplify and solve the equation.

Step 1: Notice that the denominator [tex]\(4x - 16\)[/tex] can be factored:

[tex]\[ 4x - 16 = 4(x - 4) \][/tex]

So, the equation becomes:

[tex]\[ \frac{x}{4(x - 4)} - 2 = \frac{1}{x - 4} \][/tex]

Step 2: To combine the left side over a common denominator, we need both terms to have the same denominator. The common denominator is [tex]\(4(x - 4)\)[/tex]:

[tex]\[ \frac{x - 2 \cdot 4(x - 4)}{4(x - 4)} = \frac{1}{x - 4} \][/tex]

Simplifying the numerator:

[tex]\[ x - 8(x - 4) = x - 8x + 32 = -7x + 32 \][/tex]

So, the equation now is:

[tex]\[ \frac{-7x + 32}{4(x - 4)} = \frac{1}{x - 4} \][/tex]

Step 3: Since the denominators are equal, we can set the numerators equal to each other:

[tex]\[ -7x + 32 = 4 \][/tex]

Step 4: Solve for [tex]\(x\)[/tex]:

[tex]\[ -7x + 32 = 4 \][/tex]

Subtract 32 from both sides:

[tex]\[ -7x = 4 - 32 \][/tex]

[tex]\[ -7x = -28 \][/tex]

Divide by -7:

[tex]\[ x = 4 \][/tex]

Step 5: Check if [tex]\(x = 4\)[/tex] is a valid solution by substituting in the original equation:

Substitute [tex]\(x = 4\)[/tex] in [tex]\(4x - 16\)[/tex]:

[tex]\[ 4(4) - 16 = 0 \][/tex]

This makes the denominator zero and thus the equation undefined for [tex]\(x = 4\)[/tex].

Therefore, [tex]\(x = 4\)[/tex] is not a valid solution because it leads to division by zero.

Since our earlier steps show [tex]\(x = 4\)[/tex] as the only solution, but it is invalid, we conclude that there are no valid solutions to the equation.

The answer is:
[tex]\[ \boxed{\text{No}} \][/tex]
