m-2m-2-3\left(m-1\right)=2\left(1-4m\right)
Use the distributive property to multiply -2 by m+1.
-m-2-3\left(m-1\right)=2\left(1-4m\right)
Combine m and -2m to get -m.
-m-2-3m+3=2\left(1-4m\right)
Use the distributive property to multiply -3 by m-1.
-4m-2+3=2\left(1-4m\right)
Combine -m and -3m to get -4m.
-4m+1=2\left(1-4m\right)
Add -2 and 3 to get 1.
-4m+1=2-8m
Use the distributive property to multiply 2 by 1-4m.
-4m+1+8m=2
Add 8m to both sides.
4m+1=2
Combine -4m and 8m to get 4m.
4m=2-1
Subtract 1 from both sides.
4m=1
Subtract 1 from 2 to get 1.
m=\frac{1}{4}
Divide both sides by 4.
