Answer 2

Answer:

LHS = RHS = 573/56

Step-by-step explanation:

x = 3/8

y = 6/7

z = -9

Verify That ( x + y ) -z = ( x -z ) + y

By Substituting the values,

(3/8 + 6/7) - (-9) = (3/8 - (-9)) + 6/7

By taking LCM

(21/56 + 48/56) + 9 = (3/8 +72/8) +6/7

69/56 + 9 = 75/8 + 6/7

By taking LCM,

69/56 + 504/56 = 525/56 + 48/56

573/56 = 573/56

LHS = RHS

Hence proved

Hope this will help you!!
