What are you trying to say here i mean yes it could be true if you divide it by 2 or 1.
You can solve this question with pythagorean theorem >

Based on the information, you already have one side (a or b, doesn't matter, 12) and the hypotenuse (the cut, c, 15)
So:
1.

2. 144+

= 225
3.

= 225 - 144 = 81
4.

5.
First u add ten to both sides to cancel out. Now you have 14=-7s. Since you are trying to do the opposite operation, you divide by -7 on each Sides. Now you have -2=s. Hope this helped
