Question

a table cost 200 more than a chair. the price of 2 table and 3 chair is cost 1400. find the cost of each

Answer 1

Let the cost of chair be "x"
Given that the table costs 200 more than the chair 
so the cost of the table will be "x+200"
Also given that the cost of 2 tables (i.e 2(x+200)) and 3 chairs (i.e 3x) is 1400
i.e 
2(x+200)+3x=1400
2x+400+3x=1400
5x+400=1400
5x=1400-400
5x=1000
x=1000/5
x=200

Therefore, cost of chair= x = 200
                   cost of table= x+200 = 200+200= 400. 

Answer 2

X is the cost of table and y is the cost of chair
