Question

the cost of petrol in city is rs70 per litre.Find a linear equation in two variable where "y" represents number of litre of petrol consumed and rs "X" is total cost.

Answer 1

70y/x is the linear equation

Answer 2

Answer:

$X=70y$

Step-by-step explanation:

"y" represents number of litre of petrol consumed

"x" is total cost.

We are given that the cost of petrol in city is rs70 per litre.

So, cost of 1 liter petrol = Rs.70

So, cost of y liters = 70y

Since we are given that the total cost is represented by X

So, equation becomes:

$X=70y$

Hence  a linear equation in two variable where "y" represents number of litre of petrol consumed and rs "X" is total cost is $X=70y$
