Guangming primary school pays 220 yuan for two tables and five chairs. The price of each table is three times that of each chair. How much is each table and chair

This problem is relatively simple with equation!
Let each chair be x yuan
3*2X+5X=220
6X+5X=220
11X=220
X=20
20 * 3 = 60 yuan
A: 20 yuan for each chair and 60 yuan for each table

A table costs 12 yuan more than a chair. If the unit price of a chair is 3 / 5 of that of a table, how much does it cost to buy a set of tables and chairs?

Unit price of table = 12 (1-3 / 5) = 30 yuan
Chair unit price = 30-12 = 18 yuan
One set price = 30 + 18 = 48 yuan

A table is 72 yuan more expensive than a chair. The price of a table is three times that of a chair. How much is a chair

A chair:
