Question

Write a short story on the expression the evil that men do live in not less than four hundred words

Answer 1

Explanation:

x 65 55 45 35

y 20 40 60 80

Let the cost of 1 kg of apples be x and that of

1 kg be y

So the algebraic representation can be as follows:

2x+y=160

4x+2y=300→2x+y=150

The situation can be represented graphically by plotting these two equations.

2x+y=160 ⇒y=160-2x

x 70 60 50 40 y-160-2x 20 40 60 80

2x+y=150⇒y=150-2x

x 65 55 45 35

y=150-2x 20 40 60 80

We can see that the lines do not intersect anywhere, i.e. they are parallel. Hence we can not arrive at a solution.
