If half of a number is 3, then twice the number will be

Answer 1

If half of a number is 3, then twice the number will be...

If x represents the number, "half of a number is 3" can be written as 1/2(x) = 3.

1/2(x) = 3 solve for x

x = (3)(2) to remove the 1/2, multiple both sides by 2

x = 6

The number is 6. Twice the number is 12.

You can check your work. Half of 6 is 3. Two times 6 is 12.
