Twelve less than 2 times a number is 30. find the number.?

Answer 1

Let the number be x:

2x-12 = 30

2x = 30+12

2x = 42

x = 21

Answer 2

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.
