Answer:

(x, y) = (2, -6)

Step-by-step explanation:

Subtract the first equation from the second.

(8x -2y) -(5x -2y) = (28) -(22)

3x = 6

x = 2

Substitute this into either equation and solve for y.

8(2) -2y = 28

8 -y = 14 . . . . . . . . divide by 2

y = 8 -14 = -6 . . . . add y-14 to both sides

The solution is (x, y) = (2, -6).

2. Tomás compró una bicicleta en $199.900. Primero, canceló la mitad y el resto en 7 cuotas de igual valor, con un interés total

Papessa [141]

Answer:

Cada cuota tendrá un valor de $14,850.

Step-by-step explanation:

Dado que Tomás canceló la mitad del valor de la bicicleta, la cual costaba $199.900, el valor pagado al inicio fue de $99,950 (199,900 / 2).

Luego, para el valor restante, Tomás suscribió a una financiación con un interés de $4,000, elevando el monto a pagar a $103,950, pagaderos en 7 cuotas. Por lo tanto, dichas cuotas tendrán cada una un valor de $14,850 (103,950 / 7).
