1. x + 10 = 19
x = 9
2. x - 45 = -15
x = 30
3. consecutive odd numbers: (x-1), x, (x+1)
(x-1) + x + (x+1) = 57
3x = 57
x = 19
The integers are 17, 19, and 21.
4. consecutive even numbers: (x-2), x, (x+2)
(x-2) + x + (x+2) = 84
3x = 84
x = 28
The integers are 26, 28, and 30.
5. x + 2x = 12
3x = 12
x = 4
