Answer 1

Steps: 2 Marks
Answer: 1 Mark

Price of one shirt = ₹ y

So, price of two shirts = ₹ 2y

Rahul and his cousins will get ₹ 2y after giving back two shirts.

Now, the money they spent on clothes = (Money they spent before giving back the shirts) - (Cash they get back)

= (5x + 6y) - (2y)

Like terms can be subtracted.
$\Rightarrow 6y$ and $2y$ are like terms,

$\therefore$ The money they spent on clothes
= ₹ (5x + 6y - 2y)

= ₹ (5x + 4y)
