Question

Let the cost of a pen and a pencil be Rs.$x$ and Rs.$y$ respectively. Anuj pays Rs.$34$ for $3$ pens and $2$ pencils. Write the given data in the form of a linear equation in two variables. Also represent it graphically.

Answer 1

Cost of one pen $=Rs.x$

Therefore cost of 3 pens$=Rs.3x$

Cost of one pencil$=Rs.y$

Therefore cost of 2 pencils $=Rs.2y$

Then according to question $3x+2y=Rs.34$
