15 because 10+5=15
when one number moves from left side to right side or right side to left side, signs changes;
that mean plus becomes minus and minus becomes plus

Answer:

15

Explanation:

2x-5=10?

So if you put in 7.5 instead of X, the sum will be 15

So 15-5=10.

In this case 15 will be the answer.
