Answer:
[tex]m=-\frac{1}{2}[/tex]
Step-by-step explanation:
We are given that an equation
[tex]-2m-5m-8=3+(-7)+m[/tex]
We have to find an equation which is equivalent to given equation
Combine like terms
[tex]-7m-8=-4+m[/tex]
Subtraction property of equality
[tex]-7m-m-8=-4[/tex]
Combine like terms
[tex]-8m-8=-4[/tex]
[tex]-8m=-4+8=4[/tex]
[tex]m=\frac{4}{-8}=-\frac{1}{2}[/tex]
Hence, [tex]m=-\frac{1}{2}[/tex]
