Question

write down five solution of each of the following equation X + Y is equal to zero

Answer 1

x+y=0,

five solutions are (0,0), (1,-1), (2,-2), (3,-3), (4,-4)

Answer 2

$x + y = 0 \\ x = 0 \: \: y = 0 ........( 1) \\ x = 1 \: \: \: y = - 1......(2) \\ x = 2 \: \: \: \: \: y = - 2........(3) \\ x = 3 \: \: \: \: y = - 3......(4) \\ x = 4 \: \: \: \: \: y = - 4......(5)$
