Answer» (a) As u × v = u and u = -4 ∴ -4 × v = -4 ⇒ v = l (Multiplicative identity) (b) As x × w = w. Given that x ≠ 1 ∴ x × w = w is only possible when w = 0 (c) As u + x = w, Put u = – 4 and w = 0 ∴ -4 + x = 0 ⇒ x = 4 (Transposing -4 to R.H.S.)

Answer»

(a) As u × v = u and u = -4 ∴ -4 × v = -4

⇒ v = l (Multiplicative identity)

(b) As x × w = w. Given that x ≠ 1

∴ x × w = w is only possible when w = 0

(c) As u + x = w, Put u = – 4 and w = 0

∴ -4 + x = 0

⇒ x = 4 (Transposing -4 to R.H.S.)
