Question

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

Answer 1

Step-by-step explanation:

Given -

a = -8

b = -7

c = 6

To Show :-

• (a + b) + c = a + (b + c)

Now,

→ [(-8) + (-7)] + 6 = -8 + [(-7) + (6)]

→ (-8 - 7) + 6 = -8 + -7 + 6

→ -15 + 6 = -15 + 6

→ -9 = -9

LHS = RHS

Hence,

Verified...

Answer 2

Given:-

• a = -8
• b = -7
• c = 6

To verify:-

• (a + b) + c = a + (b + c)

Solution:-

★ Putting values of a, b and c :-

[-8 + (-7)] + 6 = -8 + [(-7) + 6]

[ -8 - 7] + 6 = -8 + [ -7 + 6]

[- 15 ] + 6 = -8 + [-1]

- 9 = - 9

★ LHS = RHS

# Hence, Verified!
