Question

Cost of a book is five more than the cost of a pen.Taking cost of the book as Rs x and cost of a pen as Rs
y ,write a linear equation in two variables for the above situation and find ant two solutions.

Answer 1

Step-by-step explanation:

let y be the cost of the pen

Book = 5 more than pen = y+5=x

therefore , we have

x=y+5

or x-y=5

when x= 21 ( take any number)

y= x-5 = 21-5= 16

when x = 13

y= x-5= 13-5= 8
