Answer:
-8
Explanation:
1. Write the equation out.
2. Subtract the constant 5 from each side.
3. You are left with negative m equals 8.
4. -m is the same thing as -1m.
5. Divide each side by the coefficient, -1.
6. 8 divided by -1 equals -8.
5 - m = 13
-5 -5
------------------
-m = 8
*-m is the same thing as -1m so change the -m to -1m so you can divide by a coefficient*
-1m = 8
÷-1 = ÷-1
--------------------
m = -8
