Question

The cost of a ball pen is ₹5 less than half of the cost of a mountain pen. Write this statement as a linear rquation.

Answer 1

Hey ❗

______________________________________________

↪The linear equation will be :-

↪Let the cost of the ball pen be x

↪Let the cost of the fountain pen will be y

↪Now,

↪x = 5 - ( y / 2 )

↪Taking Lcm!!

↪x = ( 10 - y ) / 2

↪2x = 10 - y

↪2x + y - 10 = 0 is the required equation !!
