I believe your answer is:

Here’s why:  

⸻⸻⸻⸻

$\frac{m}{-3}+10 = -1 \text{ Given}\\\rule{150}{0.5}\\\rightarrow \frac{m}{-3} + 10 - 10 = -1 - 10\\\\\rightarrow \frac{m}{-3} = -11\text{ Subtraction Property of Equality}\\\\\rightarrow \frac{m}{-3} * 3 = -11*-3\\\\\rightarrow \boxed{m = 33} \text{ Muliplcation Property of Equality}$

⸻⸻⸻⸻

10 would get subtracted from each side. This would show the subtraction property of equality. The equation would multiplied by '-3' to isolate 'x'. This would show the multiplication property of equality.

Hope this helps you. I apologize if it’s incorrect.
