Question

4 chairs andthree tables cost rupees 2100 and 5 chairs
and two tables cost rupees 1750 find the cost of one chair
and one table graphically

Answer 1

Answer:

Cost of one chair is 150

Step-by-step explanation:

4x + 3y = 2100

5x + 2y = 1750

By solving we get

x = 150

Answer 2

4x + 3x=2100

7x= 2100

x= 2100-7

x=2093


Now,

5x+2x= 1750


7x =1750


x=1750-7


x=1743


One table and one chair =2093-1743
=350
