The price of a table can buy 4 chairs. The price of 6 chairs is 200 yuan cheaper than that of 2 tables. How much is a table? Lie equation
The table is 400 yuan
If the chair is x yuan, then one desk is 4 chairs and 4x, two tables and eight chairs are 8x,
If two tables cost 200 yuan more than six chairs, then 8x-6x = 200, x = 100
That is 100 yuan for chairs and 400 yuan for tables
The price of each desk is m yuan, and the chair is 170 yuan cheaper than the desk______ , M + (m-170)______ If the prices of three tables and eight chairs are equal, it is necessary to express the relationship with an equation containing letters______ ．
M-170 is the price of a chair. M + (m-170) is the total price of a desk and a chair. If the prices of three desks and eight chairs are equal, the equation with letters is 3M = 8 (m-170). So the answer is: the price of a chair, the total price of a desk and a chair. 3M = 8 (m-170)
Master Li bought a table and four chairs for 580 yuan. It is known that the price of each table is 180 yuan higher than that of each chair. Ask the price of a chair
How much is the money
If a chair costs X Yuan, a table costs (x + 180) yuan
x+180+4x=580
5x=400
x=80
It costs 80 yuan for a chair and 260 yuan for a table
