One answer #(-4, 4)#

Explanation:

Given #x + y = 0#

Therefore,

#x = -y# taking y to R.H.S.

When x = -4,

#-4 = -y# substituting the value of x in the equation above.

#y = 4#

Hence one answer is (-4, 4)

By giving ‘x’ the value ‘4’,

We get #4 = -y# or #y = -4# by multiplying minus sign on both sides.

Another answer is #(4, -4)#
