Answer 2

I can help you with your math problem.

According to Google Translate, your message in English is:

Answer in detail. Please solve urgently need for tomorrow. For two identical packs and three identical packs of cookies, they paid 510 tenge. For three of the same packs of tea and 5 packs of cookies, you need to pay 790 tenge. Find the price of a pack of tea and the price of a pack of cookies?

To solve this problem, we can use a system of linear equations. Let x be the price of a pack of tea and y be the price of a pack of cookies. Then we have:

2y + 3y = 510 3x + 5y = 790

Simplifying, we get:

5y = 510 3x + 5y = 790

To eliminate y, we can multiply the first equation by -1 and add it to the second equation:

-5y = -510 3x + 5y = 790 ___________ 3x = 280

Dividing by 3, we get:

x = 280/3

Substituting x into the first equation, we get:

5y = 510 - 2(280/3) 5y = 510 - 560/3 5y = 1530/3 - 560/3 5y = 970/3

Dividing by 5, we get:

y = 970/15

Therefore, the price of a pack of tea is 280/3 tenge and the price of a pack of cookies is 970/15 tenge. I hope this helps.
