Question

Below u,v,w and m represent different integers, where u=-4 and m not equal to 1   by using following equations ,find each of the values- U x v=u M x w=w U+m=w Find the values of -
(A) v
(B)w
(C) m​

Answer 1

Step-by-step explanation:

Given, u×v=u and u=−4

∴−4×v=−4

⇒v=1 is the multiplicative identity

(b) Given x×w=w∵x



=1

Therefore, x×w=w only possible when w=0

that is x×0=0, x



=1

So, w=0

(c) Given, u+x=w

putting u=−4 and w=0

∴−4+x=0

⇒x=4( transposing −4 to Right hand side )

So, v=1,x=4,w=0
