Q3 of 71 Page 53

Obtain a pair of linear equations in two variables from the following information:

Nilesh got twice the marks as obtained by Ilesh, in the annual examination of mathematics of standard 10. The sum of the marks as obtained by them is 135.

let marks obtained by Ilesh be x and marks obtained by Nilesh by y.

Now,


given, Nilesh got twice the marks as obtained by Ilesh.


⇒ y = 2x …[1]


Also, the sum of the marks as obtained by them is 135.


x + y = 135 …[2]


These are the two required linear equations.
