5m-3\left(7-1-\left(-2m\right)\right)=0
To find the opposite of 1-2m, find the opposite of each term.
5m-3\left(7-1+2m\right)=0
The opposite of -2m is 2m.
5m-3\left(6+2m\right)=0
Subtract 1 from 7 to get 6.
5m-18-6m=0
Use the distributive property to multiply -3 by 6+2m.
-m-18=0
Combine 5m and -6m to get -m.
-m=18
Add 18 to both sides. Anything plus zero gives itself.
m=-18
Multiply both sides by -1.
