Answer 2

Answer:

Step-by-step explanation:1.LHS x-y

-4/7-2/5

LCM of 7,5= 35

-20-14/35

-34/35

RHS y-x

2/5-(-4/7)

LCM of 5,7=35

14-(-20)/35

34/35

LHS is not equal to RHS

Hence verified

2.LHS -(x+y)

-(-4/7+2/5)

LCM of 7,5=35

-(-20+14/35)

-(-6/35)

6/35

RHS (-x)+(-y)

(4/7)+(-2/5)

LCM of 7,5=35

20+(-14)/35

6/35

LHS = RHS

Hence verified
