Question

pls solve fast....urgent help required

Answer 1

$\frac{1}{x+1} + \frac{3}{5x+1} = \frac{5}{x+4}$

LCM = (x + 1)(x + 4)(5x + 1)

(x + 4)(5x + 1) + 3(x + 1)(x + 4) = 5(x + 1)(5x + 1)

5x^2 + 21x + 4 + 3x^2 + 15x + 12 = 25x^2 + 30x + 5

8x^2 + 36x+ 16 = 25x^2 + 30x + 5

8x^2 + 6x + 11 = 25x^2

-17x^2 + 6x + 11 = 0

-17x^2 - 11x + 17x + 11 = 0

-x(17x + 11)+1(17x + 11) = 0

(-x + 1)(17x + 11) = 0

x = 1 (or) x = -11/17


Hope this helps!
