Question

The cost of half dozen eggs is the same as the cost of one packet bread. Express this in a linear
equation in two variables.

Answer 1

Consider,
the cost of one egg be = Rs. x
then again Consider  the cost of one packet of bread  be= Rs. y
Then the cost of 6 eggs would be = 6x
Acc. to Ques. the eqtion would be.

6x=y
and y-6x= 0

Answer 2

Therefore the required linear equation in 2 variables is x = 6y or x - 6y = 0

Given:

The cost of one packet of bread is the same as the cost of half a dozen eggs.

To Find:

Expression for the given statement in a linear equation in 2 variables.

Solution:

The required expression can be found using this simple approach.

Let the cost of one packet of bread be 'x' rupees.

Let the cost of one egg be 'y' rupees.

Then the cost of half of the dozen eggs is 6y rupees.

⇒ Cost of one packet of bread = Cost of half a dozen eggs

⇒ x = 6y

Therefore the required linear equation in 2 variables is x = 6y or x - 6y = 0.
