Question

If a-a-a=20 b-b-b=15 c-c-c=25 then proves a+b+c= ?

Answer 1

Answer:

-60

Step-by-step explanation:

a=-20

b=-15

c=-25

then a+b+c=-20-15-25=-60

Answer 2

The value of a+b+c is -60

Step-by-step explanation:

given :  a-a-a=20

i.e a = -20

b-b-b=15

b = -15

c-c-c=25

c = -25

thus the value are a= -20, b = -15 , c= -25

we have to find the value of a+b+c

then

= a+b+ c

= -20+ (-15) + (-25 )

= -20 -15-25

= -60

hence , The value of a+b+c is -60
