Question

hello friends please answer me fast​

Answer 1

Explanation:

Here,

Given value = a = -7 / 5 and b= 2/7

to verify = a + b = b + a

than,

LHS = a + b

-7 / 5 + 2 / 7

( -7 x 7 + 2 x 5 ) / 35

( -49 + 10 ) / 35

-39 / 35

RHS = b + a

2/7- 7 /5

(2 x 5 - 7 x 7 ) /35

(10 - 49 ) / 35

-39 / 35

Hence,

LHS = RHS proved
