Question :

A person bought 3 books and 5 boxes and paid RS.80 express this in the form of linear equation

Answer:

Let the cost of a book be x.

Cost of 3 books =

$3 \times x = 3x$

Let the cost of a box be y.

Cost of 5 boxes =

$5 \times y = 5y$

Cost of 3 books and 5 boxes = Rs.80

Therefore ,

$3x + 5y = 80 \\ \\ 3x + 5y - 80 = 0$
