Question

Find two integers whose sum is 2 and whose difference is 8.

Answer 1

a = first integer

b = second integer


a + b = 2

a = 2 - b


a - b = 8

2 - b - b = 8

2 - 2 b = 8

- 2 b = 8 - 2

- 2 b = 6

b = 6 / - 2

b = - 3


a = 2 - b

a = 2 - ( - 3 )

a = 2 + 3

a = 5

Answer 2

find two integers whose sum is 2 and whose difference is 8
