Answer:
x= 4.99
y= 0.03
Step-by-step explanation:
99x + 101y = 499-------------1
101x + 99y = 501------------2
from 1
X = (499 - 101y)/99
putting value of x in 2
(101)(499 - 101y)/99 + 99y = 501
(50399 - 10201y)/99 + 99y = 501
(50399 - 10201y + 9801y) = 501*99
50399 - 20002y = 49599
20002y = 50399 - 49599
y = 800/20002 =0.03
x = (499 - 101*800/20002)/99
= (499 - 4.03)/99
= 494.97/99
= 4.99
