how do you wok this x+4=-x-4

Question

what is this awser

Answer 1

x+4=-x-4

 

  2x + 4 = -4             [add x to both sides]

  2x = -8                   [subtract 4 from both sides]

   x = -4

 

Check:

  Is   (-4) + 4 = -(-4) - 4   ?

              0  =  4 - 4   ?

              0  =  0   ? yes

Answer 2

x + 4 = -x - 4

2x + 4 = - 4      add x to both sides

2x = - 4            subtract 4 from both sides

 

Can you solve for x and answer?
