5. Given 1 / A-1 / b = 4, then the value of (a-2ab-b) / (2a-2b + 7ab) is equal to____ 5. Given that (1 / a) - (1 / b) = 4, then the value of (a-2ab-b) / (2a-2b + 7ab) is equal to____ 6. If the value of fraction (3x & # 178; - 6x) / (2-x) is 0, then the value of X is 0____ When x____ The fraction (1 + 2x) / (1-2x) is significant 10. If 1 / x + x = 3, then (the fourth power of X + X & # 178; + 1) / X & # 178____

5. Given that (1 / a) - (1 / b) = 4, then the value of (a-2ab-b) / (2a-2b + 7ab) is equal to____ B-A = 4AB (a-2ab-b) / (2a-2b + 7ab) = (- 4ab-2ab) / (- 8ab + 7ab) = 66. If the value of fraction (3x & # 178; - 6x) / (2-x) is 0, then the fraction is meaningless when the value of X is 2. If x ≠ 1 / 2, the fraction (1 + 2
