Question

2. Verify that a=(b+c)=(a+b)+(a=c)for each of the following values of a bande
(a) a = 12,6 =-4.c=2
(b) a = (-10), b= 1.c=1​

Answer 1

Answer:

$a) \\ a = 12 \\ b = - 4 \\ c = 2 \\ a = (b + c) + (a + b) + (a + c) \\ 12 = ( - 4 + 2) + (12 + - 4) + (12 + 2) \\ 12 = - 2+ 8 + 14 \\ 12 = - 2 + 24 \\ 12 = + 22 \\ it \: is \: not \: equal \\ \\ b) \\ a = - 10 \\ b = 1 \\ c = 1 \\ a = (b + c) + (a + b) + (a + c) \\ - 10 = (1 + 1) + ( - 10 + 1) + ( - 10 + 1) \\ - 10 = 2- 9 - 9 \\ - 10 = 2 - 18 \\ - 10 = - 16 \\ 10 = 16 \\ it \: is \: also \: not \: equal$
