Let's represent the number as "x". The given equation can be written as 2x - 12 = 30. Adding 12 to both sides, we get 2x = 42. Finally, dividing both sides by 2, we find that x = 21. So, the number is 21.
Let the number be x:
2x-12 = 30
2x = 30+12
2x = 42
x = 21
The answer is 6.

3x + 5 < 12
twelve
Let the number be x: 4x-12 = 6x 4x-6x = 12 -2x = 12 x = -6
