Answer 2

Given :- A person bought 3 books and 5 boxes and paid rs.80 express in the form of linear equation .?

Answer :-

Let us assume that, cost price of a book is Rs.x

so,

→ cost price of 3 books = 3 * cost price of 1 book = 3 * x = Rs.3x .

also, Let us assume that, cost price of a box is Rs.y

so,

→ cost price of 5 boxes = 5 * cost price of 1 box = 5 * y = Rs.5y ...

then,

→ Total cost = Rs.80

→ cost price of 3 books + cost price of 5 boxes = 80

→ 3x + 5y = 80 = Required Linear equation .
