Question

the cost of a geometry box thrice the cost of a compass. write the linear equation in two variable to represent this statement ​

Answer 1

Let the cost of a pen be x and the cost of a pencil be y
According to the statement, cost of a pen is thrice the cost of a pencil
⇒x=3y
⇒x−3y=0 which is a linear equation in two variables

Answer 2

Let the cost of a pen be x and the cost of a pencil be y

According to the statement, cost of a pen is thrice the cost of a pencil

⇒x=3y

⇒x−3y=0 which is a linear equation in two variables
