Question

Verify x+y =y+x if x=5/7 and y=-3/2​

Answer 1

answer:

-0.78

Step-by-step explanation:

((5/7)+(-3/2))= -0.78

((-3/2)+(5/7))= -0.78

Answer 2

Step-by-step explanation:

x = 5/7

y = -3/2

x+y

= 5/7 + (-3/2)

= 5/7 - 3/2

= 5*² - 3*⁷/14

= 10 - 21/14

= 11/14 → LHS

y+x

= -3/2 + 5/7

= -3*⁷ + 5*²/14

= -21 + 10/14

= 11/14 → RHS

11/14 = 11/14

i.e

LHS = RHS

Therefore, x+y=y+x according to commutative property of addition
