x+y = 20
x-y = 30
add the 2 equations
2x = 50
then, x = 25
25 + y = 20
y = 20 - 25
then, y = -5
so, x= 25 and y = -5
x-y = 30
add the 2 equations
2x = 50
then, x = 25
25 + y = 20
y = 20 - 25
then, y = -5
so, x= 25 and y = -5

On solving the the two lineare equations
we get x=25
and y=-5.
we get x=25
and y=-5.
