Question

verify X+Y=Y+X for X=5/7andY=-3/2​

Answer 1

X + Y = Y + X

At x = 5/7 and y = - 3/2

• LHS = X + Y

5/7 + ( -3/2 )

5/7 - 3/2

( 10 - 21 ) / 14

- 11/14

• RHS = Y + X

- 3/2 + 5/7

( - 21 + 10 ) 14

- 11/14

LHS = RHS

Hence proved .

Answer 2

(-11)

14

Step-by-step explanation:

X+Y = Y+X

5/7+(-3/2)

LCM of 7 and 2 = 14

2×5+7×-3

14

10+(-21)

14

=(-11)
