Answer 2

Answer:

x=3,y=1

Step-by-step explanation:

21x+47y=110 - (1)

47x+21y=162 - (2)

MULTIPLYING EQUATION (1) BY 21,WE GET

441x+987y=2310 - (3)

MULTIPLYING EQUATION (2) BY 47,WE GET

2209x+987y=7614 - (4)

NOW,SUBTRACT (4)—(3) WE HAVE,

(2209x+987y) — (441x+987y)=7614-2310

1768x=5304

=) x=5304÷1768=3

x=3

NOW SUBSTITUTE X=3 IN EQUATION (1)

21×3+47y=110

47y=110-63

y=47÷47=1

THERFORE,

X=3,Y=1
