Question

If 100x+500y=19,900 then what is the value of x and y ?​

Answer 1

Step-by-step explanation:

one equation..

100x+500y = 19900

100x = 19900-500y

x = 19900 -500y/100

and value of y is ,

100x + 500y = 19900

500y = 19900-100x

y = 19900-100x/500

here's no second equation so cannot find real value of x and y.
