Answer:
1) Let us take the following example:-
We have Rs 60 with us and we need to buy 5 pens and 1 scale.
⇒ Let the cost of one pen be x
Let the cost of scale be y
EQUATION FORMED!
5x + y = 60 (because we need to buy 5 pens)
2) Let us now take a different example:-
We have Rs 60 with us and we need to buy 1 mathematical instruments box and 2 pencils. But when we reach the shop, we find out that we are less of Rs 40.
⇒ Let the cost of the mathematical box be x
Let the cost of one pencil be y
EQUATION FORMED:
x + 2y = 60 + 40 (because we have Rs 40 less)
x + 2y = 100
