Let’s denote the unknown number as x. According to the problem, we can translate the statement into a mathematical equation:
Twice the number: 2x
Half the number: 0.5x
Now, according to the information provided, we can set up the equation:
2x = 0.5x + 27
Next, we need to isolate x. To do this, we can subtract 0.5x from both sides:
2x – 0.5x = 27
This simplifies to:
1.5x = 27
Now, we can solve for x by dividing both sides by 1.5:
x = 27 / 1.5
When we calculate that, we find:
x = 18
Thus, the number we are looking for is 18.
