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
