Question

The cost of 5 pencil is equal to the
cost of 2 ballpoint pen. write a linear
equation in two variables to
represent this statement. (take the
cost of a pencil to be x and the
ballpoint pen to be *y)
Your answer​

Answer 1

Answer:

5x - 2y = 0

Step-by-step explanation:

Let the cost of pencil be x Rs and cost of ball point be y Rs.

According to question,

The cost of 5 pencil is equal to the cost of 2 ballpoint pen.

ᴛʀᴀɴsʟᴀᴛɪᴏɴ :

5x = 2y

→ 5x - 2y = 0

Hence, linear equation in two variables will be 5x - 2y = 0.

________________

• linear equation is having higest power or degree as 1.

Answer 2

Answer :

Let, cost of a pencil be x and cost of a ballpoint pen be y.

Then, reading out the given statement we can conclude that,

⇒5x = 2y

As cost of 5 pencils is equal to cost of 2 ballpoint pens. Where, x and y are cost of each pencil and ballpoint pen respectively.

So, moving ahead

⇒5x - 2y = 0

Bring 2y to the LHS from RHS, so sign of 2y will be taken as - 2y in LHS.

Hence, equation is 5x - 2y = 0
