Assuming that you have no typos, deal with like terms first.
3/x - 4/x = -1/x
1/1 = 1
-5+1-5 = -9
This gives me -1/x -9

Unless the plus sign is supposed to be negative, you will not get 2x/3.
Because of apparent typos, I am not even going to deal with the division problem. However, I hope what I did helps. Thanks for asking.

To check the first answer, let's evaluate the expression step by step:
The expression is: 3/(x-5) + 1/(1-4/(x-5))
First, simplify the denominator of the second fraction: 1 - 4/(x-5)
To do this, we need to find a common denominator of (x-5). Multiply 1 by (x-5)/(x-5), which gives us (x-5)/(x-5). The expression becomes:
1 - 4(x-5)/(x-5)
Next, simplify the first fraction: 3/(x-5)
Now, we need to find a common denominator for both fractions, which is (x-5). Multiply the numerator and denominator of the first fraction by (1-4/(x-5)):
3(1-4/(x-5)) / (x-5)
Distribute the 3:
(3 - 12/(x-5)) / (x-5)
Combine the numerators:
(3 - 12/(x-5)) / (x-5) = (3(x-5) - 12) / (x-5)
Simplify the numerator:
(3x - 15 - 12) / (x-5) = (3x - 27)/(x-5)
Therefore, the simplified expression is (3x - 27)/(x-5).
To check the second answer, let's evaluate the expression step by step:
The expression is: (x^2-49y^2) / (6x^2+42y) / (x^2-7xy)
To divide fractions, we need to multiply by the reciprocal of the second fraction:
(x^2-49y^2) / (6x^2+42y) * (x^2-7xy)
Factorize the numerator and denominator:
[(x+7y)(x-7y)] / [6(x^2+7y)] * (x^2-7xy)
Simplify the expression:
[(x+7y)(x-7y)(x^2-7xy)] / [6(x^2+7y)]
After expanding the numerator and canceling common factors, we get (x+7y)(x^2-7xy) / 6(x^2+7y).
Therefore, the simplified expression is (x+7y)(x^2-7xy) / 6(x^2+7y).
To check the third answer, let's evaluate the expression step by step:
The expression is: x/6 + 3x/6
The denominators are the same, so we can add the numerators:
(x + 3x) / 6 = 4x / 6
The numerator (4x) is divisible by 2, and the denominator (6) is divisible by 2, so we can simplify the fraction by dividing both numerator and denominator by 2:
(4x / 6) = (2x / 3)
Therefore, the simplified expression is 2x/3.
Based on the calculations, the first answer should be (3x - 27)/(x-5), the second answer should be (x+7y)(x^2-7xy) / 6(x^2+7y), and the third answer should be 2x/3.
