Step-by-step explanation:

4.[consider 4 as 'x']

a) 4+(4)=0

   8=0

∴The following equation is not equal.

b) 4-(4)=0

   0=0

∴The following equation is equal.

c)4+(4)=-2x4

  8=-8

∴The following equation is not equal.

d)4=-1x1

  4=-1

∴The following equation is not equal.

5.[consider -4 as 'x']

a)-4x(-4)=0

  8=0

∴The following equation is not equal.

b)-4-(-4)=0

  -4+4=0

  0=0

∴The following equation is equal.

c)-4+(-4)=2x(-4)

  -4-4=-8

  -8=-8

∴The following equation is equal.

d)-4-(-4)=-2x(-4)

  -4+4=8

  0=8

∴The following equation is not equal.

6.[consider 4 as 'x']

   2-4=-2

a)2-4=-2

∴first equation is equal to 2-x.
