Question

The cost of ball pen is ₹5 less than half of the cost of fountain pen. Write this statement as a linear equation in two variables

Answer 1

Let the cost of fountain pen be x and the cost of ball pen be y.
So according to question the linear equation formed will be:
(x/2)-5=y
=>x/2=y+5
=>x=2*(y+5)
=>x-2y=10

Answer 2

Answer:Let the cost of fountain pen be x and the cost of ball pen be y.

So according to question the linear equation formed will be:

(x/2)-5=y

=>x/2=y+5

=>x=2*(y+5)

=>x-2y=10
