Answer 1

Answer:

price of a pen 14 rupees

price of the book 5 rupees

Answer 2

Answer:

cost of book is 12 and cost of pen is 7.

Step-by-step explanation:

let let the value of book to be X and that of pen to be y .

so according to the question,

x+y = 19

and x= y+5

= x+y= 19 and x-y = 5

adding both equations,

x+y+x-y = 24

= 2x = 24

= x= 12

x+y= 19

= 12+y = 19

y = 19-12 = 7
