Question

verify a-(b-c) ≠(a-b) +(a-c) for a=15, b=-2, c=-1​

Answer 1

Step-by-step explanation:

15-(-2-1) =/ (15-(-2)) + (15-(-1))

15-(-3) =/ (15+2) + (15+1)

15+3 =/ 17+16

18 =/ 33

=/ This means it is not equal to

Answer 2

Step-by-step explanation:

a-(b-c)un equal(a-b)+(a-c)

15-{(-2-(-1)}un equal(15-(-2))+(15-(-1))

15-(-2+1) un equal(15+2)+(15+1)

15-(-1) un equal(17)+(16)

15+1 un equal 17+16

16 un equal to 33
