Question

three chairs and two tables cost rupees 700 and 5 chairs and 3 tables cost rupees 1100 what is the cost of two chairs and 2 tables​

Answer 1

Answer:

3x + 2y= 700____(equation1 )× 3

5x + 3y= 1100____(equation 2) ×2

9x+ 6y= 2100 ____1

10x+ 6y = 2200____2

Subtract 2 from 1

X= 100

by putting the value of x in eq 1

9× 100 + 6y= 2100

6y = 1200

y= 200
