Question

Plz anwer number (ii)

Answer 1

Dear Friend,
x=2
y=4/5
z=-3/10
LHS:-
(x+y)z
=(2+4/5)(-3/10)
=(14/5)(-3/10)
=-21/25
RHS:-
x×z+y×z
=2(-3/10)+(4/5)(-3/10)
=-3/5-6/25
=(-15-6)/25
=-21/25
So, LHS = RHS
Hence proved.
hope it benefits u.

Answer 2

(2+4/5)*-3/10                     =(2*-3/10)+(4/5*-3/10)
14/5*-3/10                            -3/5 -12/50
-42/50                                    -42/50
instead of = there should be line for rhs and lhs
