Answer:
The three numbers are -4, 0, and 1.
The sum of three numbers is -3: -4 + 0 + 1 = -3
If the second number is subtracted from the sum of the first and third numbers, the result is -3: (-4 + 1) - 0 = -3
If the third number is subtracted from the sum of the first and second numbers, the result is -5: (-4 + 0) - 1 = -5
Explanation:
x --> first number
y --> second number
z --> third number
x + y + z = -3
(x + z) - y = -3
(x + y) - z = -5
x = -3 - y - z
(-3 - y - z + z) - y = -3
-3 - y - y = -3
-2y = 0
y = 0
(-3 - y - z + y) - z = -5
-3 - z - z = -5
-3 - 2z = -5
-2z = -2
z = 1
x = -3 - 0 - 1
x = -4
