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

[tex]\[ \frac{x}{x-4} - \frac{8}{4-x} = 2 \][/tex]

[tex]\[ x = \ ? \][/tex]


Sagot :

To solve the equation [tex]\(\frac{x}{x-4}-\frac{8}{4-x}=2\)[/tex], let's follow these steps:

1. Identify the given equation:
[tex]\[ \frac{x}{x-4} - \frac{8}{4-x} = 2 \][/tex]

2. Simplify the second term:
Notice that [tex]\(4 - x\)[/tex] can be rewritten as [tex]\(-(x - 4)\)[/tex], so:
[tex]\[ \frac{8}{4-x} = \frac{8}{-(x-4)} = -\frac{8}{x-4} \][/tex]
Substituting this into the original equation, we get:
[tex]\[ \frac{x}{x-4} - \left(-\frac{8}{x-4}\right) = 2 \][/tex]
Simplifying further:
[tex]\[ \frac{x}{x-4} + \frac{8}{x-4} = 2 \][/tex]

3. Combine the fractions:
Both fractions have the same denominator. Therefore, we can combine them:
[tex]\[ \frac{x + 8}{x-4} = 2 \][/tex]

4. Clear the fraction by multiplying both sides by the denominator:
Multiply both sides by [tex]\(x-4\)[/tex]:
[tex]\[ x + 8 = 2(x - 4) \][/tex]

5. Simplify the resulting equation:
Distribute the 2 on the right-hand side:
[tex]\[ x + 8 = 2x - 8 \][/tex]

6. Solve for [tex]\(x\)[/tex]:
Rearrange the equation to solve for [tex]\(x\)[/tex]:
[tex]\[ 8 + 8 = 2x - x \][/tex]
[tex]\[ 16 = x \][/tex]

Therefore, the solution to the equation [tex]\(\frac{x}{x-4} - \frac{8}{4-x} = 2\)[/tex] is:
[tex]\[ x = 16 \][/tex]
