Question

2 chairs and 1 table cost = 170and 5 chairs and 4 table cost=530 then the cost of 1 chair​

Answer 1

Step-by-step explanation:

let cost of single chair and table be x, y respectively.

according to question,

2x+y=170 (1)

5x+4y=530 (2)

from (1) y=170-2x

so, (2) becomes 5x+4(170-2x)=530

hence u will get the required cost of chair

Answer 2

let the price of chair be X and price of table be Y
now by solving linear equation in two variable
2X + Y = 170 eq 1
5 x + 4 Y= 530 eq 2
by solving equation 1 and 2
2(2 X + Y=170 )=4x+2y=680
5x+4y. =530
therefore value of x is 50 and value of Y is 70
