Question

I need the answer ASAP, I can’t find a single person who has the same problem (I’m not very good at math)

Answer 1

Answer: 4

Explanation:

Answer 2

4

Explanation:

3(-5x-5) + 19x = _x - 15

-15x-15+19x = _x - 15

4x - 15 = _x - 15

It has to be the same on both sides so 4 would go in that blank.
