Step-by-step explanation:

let the cost of a table =x

cost of chair =y

ATQ,

4x+3y=2250

=>4x+3y-2250=0............(i)

3x+4y=1950

=>3x+4y-1950=0.............(ii)

x/b1c2-b2c1= y/c1a2-c2a1= 1/a1b2-a2b1

=>×/-5850-(-9000) =y/-6750-(-7800)=1/16-9

=>x/3150=y/1050=1/7

=>x=450

=>y=150

hence, cost of 1 table = 450

and cost of 1 chair= 150
