Answer 1

answer is 30 soo be with me

Answer 2

Answer:

$x=70y$

Step-by-step explanation:

Given : The cost of petrol in a city is rs 70 per liter.

To Find: find a linear equation in two variables where y represents number of liters of petrol consumed and rs x is total cost

Solution:

Let y be number of liters of petrol consumed

Since  cost of petrol in a city is rs 70 per liter.

So, cost of y liters = Rs . 70 y

Since we are given that rs x is total cost

So, A.T.Q

$x=70y$

Hence  a linear equation in two variables where y represents number of litres of petrol consumed and rs x is total cost is $x=70y$
