Answer:
-5 (ans)
Step-by-step explanation:
= x + 3 / x + 2 = 3x - 7 / 2x - 3
cross multiply
= x+3 (2x-3) = x+2 (3x-7)
= 2x² - 3x + 6x - 9 = 3x² - 7x + 6x - 14
= -9 + 14 = 3x² - 2x² -x - 3x
= 5 = x² - 4x
= 0 = x² - 4x - 5
factorise, x² - 4x - 5
Factor: (x - 5)(x + 1) = 0
If x = -1, then x - 4 = (-1) - 4 = -5
therefore,
answer = -5
