Question

3. Given: (i) a = 18, b = -3, c = 2
(ii) a = (-20), b = -1, c = -1
Verify that a = (b c) + (a - b) = (a + c) for each of the above stated values of a, b and c

Answer 1

Step-by-step explanation:

a=(b c)+(a-b)=(a+c)

18=(-3×2)+(18-(-3))=(18+2)

18=-6 +18+3=20

18=15=20

-20=(-1×-1)+(-20-(-1))=(-20-(-1))

-20=1-20+1=-20+1

-20=-18=-19

I think your question is because this question is not verify
