A desk is 10 yuan more expensive than a chair. The unit price of a chair is three fifths of that of a desk. What are the unit prices of a desk and a chair? Write the equivalent relation. Write the comprehensive formula. Solution is the meaning of formula

Table: X, chair: y
X-Y=10
Y=3/5X
The solution is x = 25
Y=15
So the table costs 25 yuan and the chair 15 yuan

A desk costs 10 yuan more than a chair. If the unit price of a chair is 35 yuan of that of a desk, how much is the unit price of the desk and chair?

Suppose the unit price of the desk is x yuan, then the unit price of the chair is 35x. According to the meaning of the question, we get that x-35x = 10 & nbsp; & nbsp; & nbsp; & nbsp; 25X = 10 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 25 (yuan) & nbsp; & nbsp; 35x = 35 × 25 = 15 (yuan)
