Question

If 7 is subtracted from half of a number, the result is 14. Find the number.

Answer 1

Hey there! :-)

Let the unknown number be s.

"half of a number" means we divide s by 2.

We write it like so:

$\frac{s}{2}$

Now, the problem says that we subtract 7:

$\frac{s}{2} -7=14$

• s/2-7=14
• s/2=14+7
• s/2=21
• Multiply both sides by 2:
• s=42

Therefore, the number is 42. Hope this helps! :)

Answer 2

• If 7 is subtracted from half of a number, the result is 14.
• Let the number be x.
• Therefore, by the problem
• $\frac{x}{2} - 7 = 14 \\ = > \frac{x}{2} = 14 + 7 \\ = > \frac{x}{2} = 21 \\ = > x = 21 \times 2 \\ = > x = 42$

Answer:

The number is 42.

Hope you could get an idea from here.
