Answer 2

Step-by-step explanation:

➣ $\bf\underline{\underline{\red{Given :}}}$

• a belt and wallet cost 42. 7 belt and 4 wallets cost 213. Find the cost of each them.

➣ $\bf\underline{\underline{\red{To \: Find :}}}$

• The cost of each of them.

➣ $\bf\underline{\underline{\red{Solution :}}}$

Let, the cost of a belt = x

Cost of a wallet = y

‏‏‎ ‎

↪According to the question,

⇒x + y = 42

⇒7x + 4y = 213

‏‏‎ ‎

➥ Now multiply first equation by 4.

⇒4x + 4y = 168

‏‏‎ ‎

➥ Substitute it from 2nd equation,

⇒3x = 45

⇒x = 15

‏‏‎ ‎

➥ Now, substitute it in 1st equation,

⇒15 + y = 42

⇒y = 42 - 15 = 27

‏‏‎ ‎

∴ Cost of Belt = $ 15

ㅤ Cost of Wallet = $ 27

‏‏‎ ‎

➣ $\bf\underline{\underline{\red{Final \: Answer :}}}$

• Cost of Belt = $ 15
• Cost of Wallet = $ 27
