Answer 2

Answer:

X=2022 & y=797

Step-by-step explanation:

x+y=2820 -------(i)

and

x-y=1224---------(ii)

from eq (i)

y=2820-x-------(iii)

putting eq (iii) in eq (ii) we get,

x-y=1224

X-(2820-X)=1224

X+X-2820=1224

2X=1224+2820

X=4044

2

X=2022. -----------(iv)

putting valueof X in eq. iii

y=2820-2023

=797
