Question

Calcula el valor de “y” al resolver el sistema:
xz = 250
(x + y)x = 1000
(x + y)z = 100

Answer 1

Respuesta:

Y=-48

Explicación paso a paso:

xz=250

z = $\frac{250}{z}$

(x + y) x Z = 1000

Y =  $\frac{1000-x^{2} }{x}$

( x + y) x z =100

( x + $\frac{1000-x^{2} }{x}$ ) ($\frac{250}{z}$) =100

($\frac{x^{2} +1000-x^{2} }{x}$) ($\frac{250}{z}$)=100

$\frac{250000}{x^{2} }$ = 100

$x^{2}$ = $\frac{250000}{100}$

x= 50

(50+y) x50 =100

Y=-48
