STD 9 th . Chapter Pairs of Equation.
The cost of 4 chairs and 5 tables is Rs.6600/- and the cost of 5 chair's and 3 table's as Rs.5000/- at the same prices . What are the prices of table and chair. Don't spam​

Answer 1

Answer:

Let cost of chair be x and cost of table be y

The linear equation is

4x+5y=3200

take x=5

4(5)+5y=3200

5y=3200-20

5y=3180

y=636

therefore the first solution is

(5 , 636)

if we take y=4

4x+5(4)=3200

4x=3200-20

4x=3180

x=795

therefore the second solution is (795 , 4)
