Answer 1

*Question:-

Verify that x + y = y + x if x = 7/18 y = 4/15

(Hint: LHS=RHS = 59/90)

*Answer:-

→ x = 7/18

→ y = 4/15

→ x + y = y + x

→ 7/18 + 4/15 = 4/15 + 7/18

→ 35 + 24/90 = 24 + 35/90

→ 59/90 = 59/90

Hence L•H•S = R•H•S.

Answer 2

Step-by-step explanation:

L. H. S

(- 7/8) +(-4/15)=. - 105-32/120

= - 137/120

R. H. S

(-4/15) +(-7/8)=. - 32-105/120

=. - 137/120

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

Hence, it is verified that x+y=y+x
