Question

If a = -8, b = -7, c = 6, verify that (a + b) + c = a +(b + c).

Answer 1

Hey!!!

Solution :

Since,

a = -8

b = -7

c = 6

Substituting the given values in the equation (a + b) + c = a + (b + c)

•°• (-8 + -7) + 6 = -8 + -7 + 6

» -8 -7 + 6 = -8 -7 + 6

» -9 = -9

» L.H.S = R.H.S

•°• Verified

Hope it helps :)

Answer 2

Answer:

Hence proved

LHS = RHS = -9

Step-by-step explanation:

{(-8) + (-7)} + 6 = (-8) + {(-7)+6}

(-15) + 6 = (-8) + (-1)

-9 = -9
