Question

Calcula x
(x-1)/2 - (x-2)/3 - (x - 3)/4 = - (x-5)/5​

Answer 1

Respuesta:

x-1/2- (x-2)×(x-3)/12=x-5/5

x-1/2- x^2-5x+6/12 = x-5 / 5

30 (x-1) -5( x^2 - 5x+6) = -12(x-5)

55x-60-5x^2+12x -60 =0

67x-120-5x^2=0

-5x^2+67-120=0

5x^2-67+120=0

$x1 = \frac{67 + \sqrt{2089} }{10}$

$x2= \frac{67 - \sqrt{2089} }{10}$
