Answer :
[tex]-2m+4m+5=-3 \ \ \ |\hbox{substraction 2m from 4m} \\
2m+5=-3 \ \ \ |\hbox{substraction 5 from both sides}\\
2m+5-5=-3-5 \\
2m=-8 \ \ \ |\hbox{division by 2} \\
m=-4[/tex]
I haven't done anything yet.
Here's what you could do with it:
-- Combine the -2m and the 4m on the left side. Together, they make 2m .
Now the equation is: 2m + 5 = -3
Subtract 5 from each side: 2m = -8
Divide each side by 2 : m = -4
