Answer:

x = 5, y = 7, z = 12

Step-by-step explanation:

<u>Let the numbers be x, y and z</u>

x + y + z = 24
2y = z + 2
z = x + y

<u>Solving by substitution:</u>

x + y + z = z + z = 24
2z = 24
z = 12

2y = z + 2
2y = 12 + 2
2y = 14
y = 7

z = x + y
x = z - y
x = 12 - 7 = 5

<u>The answer:</u>

x = 5, y = 7, z = 12
