-2m+4m+5=3
(-2m+4m)+(5)=3
2m+5=3
2m+5-5=3-5
2m=-2
2m/2=-2/2
m=-1

Step-by-step explanation:
I don't know how to explain it very well but the line starts at 2 then ends at 8
Dividing by 3,600
1
Determine the number of seconds you have. This information should be given, or it should be a figure you calculated yourself.
For example, you might be converting 2,400 seconds into hours.
ivide the number of seconds by 3,600. Note that there are 3,600 seconds in one hour.[1] So, if you have more than 3,600 seconds, your conversion will be greater than hour. If you have less than 3,600 seconds, your conversion will be a fraction of an hour.
3
Convert your decimal to minutes. This step is helpful if you are working with a number of seconds equal to less than an hour, so that you can gauge how long a certain decimal is. To convert the decimal to minutes, multiply it by 60.[2]
3200 seconds = 0.88888889 Hours
(rounded to 8 digits)
