1)Below u , v , w and x represent different integers , where u = -4 and x is no equal to 1 . By using the following equations , find each of the values :

u * v = u

x * w = w

u + x = w

a) v

b)w

c)x

Explain your reasoning using the properties of integers .

Here , given; u = -4 and x 1
Now considering the first equation , we have;
u×v = uv = uu = 1
Considering the second equation, we have;
x×w = wx = ww = 1  {Although it is mentioned in the question that x is not equal to 1}
Considering third equation, we have;
u+x = w-4+1 = ww = -3
