Question

The sum of two numbers is 8. Is it possible for the difference of the two numbers to also be 8? Why or why not?

Answer 1

a+b = 8
a-b or b-a = 8?

Answer 2

try plugging numbers in, such as 8 and 0 for a and b

Answer 3

i have to explain if its possible or not

Answer 4

Yes, it is possible for two numbers to have a difference of 8 and a sum of 1.

Answer 5

two numbers: a and b
sum is 8
So a + b = 8
now a - b or b - a = 8?
plug in numbers for a and b and see if they satisfy the second statement

Answer 6

Thx ^﹏^

Answer 7

- for example
suppose a +b = 8 => a = 8 - b

in case of a -b = 8 than you substitute the 8 - b in place of a you get

8 - b - b = 8

8 - 2b = 8

- 2b = 0

b = 0 and now than substitute this b value of 0 in place of b inside this equation

a +b = 8 so a + 0 = 8 => a = 8

so for a = 8 and b = 0 it's possible or invers a = 0 and b = 8

hope helped easy understandably
