Answer:
We have, 3x−5y−4=0
⇒3x−5y=4...(i)
Again 9x=2y+7
⇒9x−2y=7...(ii)
By Elimination Method:
Multiplying equation (i) by 3, we get
9x−15y=12...(iii)
Subtracting (ii) from (iii), we get
9x−15y=12
9x−2y=7
−13y=5
⇒y=−

Answer:
Let the price of a chair be x and that of a table be y.
By the given conditions,
- x + y = 5000 ... ...(1)
- y = x + 2000 ... ...(2)
Substituting y = x + 2000 in (1), we get
- x + x + 2000 = 5000
- or, 2x = 3000
- or, x = 1500
Putting x = 1500 in (2), we get
- y = 1500 + 2000
- or, y = 3500
Answer:
- a) price of a chair is Rs. 1500
- b) price of a table is Rs. 3500
