Question

The sum of three numbers is 1. If the second number is subtracted from the sum of the first and third numbers, the result is -5. If the third number is subtracted from the sum of the first and second numbers, the result is -3. Find the three numbers.

Answer 1

final answer:

a (first number) = - 4

b (second number) = 3

c (third number) = 2

Explanation:

1. put the equation in numbers and letters:

a + b + c = 1

(a + c) - b = - 5

(a + b) - c = - 3

2. Use one of the equations to solve the other

bla bla bla

too long to explain but I got the final answer
