Question 191962: solve
9/(x^2-36) + 2/(x-6) = 1/(x+6)



both parts of the equation are fractions, 9 is the numerator in the first fraction and 2 is the numerator in the second fraction, hopefully that makes sense


thank you soo much!

9%2F%28x%5E2-36%29+%2B+2%2F%28x-6%29+=+1%2F%28x%2B6%29+ Start with the given equation.


9%2F%28%28x-6%29%28x%2B6%29%29+%2B+2%2F%28x-6%29+=+1%2F%28x%2B6%29+ Factor the first denominator


Multiply EVERY term by the LCD %28x-6%29%28x%2B6%29 to clear out the fractions.



9%2B2%28x%2B6%29=1%28x-6%29 Multiply and simplify


9%2B2x%2B12=x-6 Distribute.


2x%2B21=x-6 Combine like terms on the left side.


2x=x-6-21 Subtract 21 from both sides.


2x-x=-6-21 Subtract x from both sides.


x=-6-21 Combine like terms on the left side.


x=-27 Combine like terms on the right side.

Answer:

So the solution is x=-27
