Answer:
y=2x-10
2y=x-8
since the second equation equals 2y and the first is y that means the first equation times 2 equals the other one
4x-20=x-8
-x
3x-20=-8
+20
3x=12
x=4
then lets just plug it in
2y=4-8
simplefy
2y=-4
y=-2
(4,-2)

Responder:
$ 11,137
Explicación paso a paso:
Como no se nos dice qué encontrar, también podemos encontrar el beneficio obtenido por la venta de 351 unidades de radio.
Dado
Función de costo C (x) = 43x + 1850
Función de ingresos R (x) = 80x
Obtener la función de ganancias
P (x) = R (x) - C (x)
P (x) = 80x - (43x + 1850)
P (x) = 80x - 43x - 1850
P (x) = 37x - 1850
Si se fabrican 351 radios, la ganancia obtenida se calculará como se muestra a continuación:
P (351) = 37 (351) - 1850
P (351) = 12,987-1850
P (351) = 11,137
<em>Por lo tanto, la ganancia obtenida de las ventas de 351 radios es de $ 11,137</em>
