what is the price of a television ?
a. 1,848
b. 3840
c. 31,680
d. 3.360​

Answer 1

Step-by-step explanation:

let price of radio is x Rs and price of television is y Rs

According to the question

first

6x+4y=18480

6x=18480-4y

x=18480/6-4y/6 ---------(i)

second

14x+2y=18480 -----------(ii)

put the value of x in equation (ii)

14(18480/6-4y/6)+2y=18480

14(380-4y/6)+2y=18480

5320-56y/6+2y=18480

-56y/6+2y=18480-5320
