Question

-3/5x=-36+3x
cuando es me ayudannn xfaa​

Answer 1

Respuesta:

$\frac{ - 3}{5x} = - 36 + 3x \\ - 3 = 5x( - 36 + 3x) \\ - 3 = - 180x + 15 {x}^{2} \\ 15 {x}^{2} - 180x + 3 = 0 \\ x1 = \frac{ - ( - 180) + \sqrt{ {( - 180)}^{2} - 4(15)(3)} }{2(15)} \\ x1 = \frac{180 + \sqrt{32400 - 180} }{30} \\ x1 = \frac{180 + \sqrt{32220} }{30} \\ x2 = \frac{ - ( - 180) - \sqrt{ {( - 180)}^{2} - 4(15)(3)} }{2(15)} \\ x2 = \frac{180 - \sqrt{32400 - 180} }{30} \\ x2 = \frac{180 - \sqrt{32220} }{30}$
