Answer 2

Answer:

Proved L. H. S = R. H. S

Step-by-step explanation:

L. H. S =  3/5 (-1/7 - (5/14) =  3/7 * ( - 2 - 5)/ 14 = 3/5 * (-7/14) = -21/70 = -3/10

R. H. S =  3/5 * (-1/7) - 3/5 * (5/14) = -3/35 - 3/14 = (-6 - 15 / 70)

=  (- 21/ 70)

= - 21/ 70

= - 3/10

It follows distributive law of addition.

Hence Proved L. H. S = R. H. S
