3+12n-2\left(5n-3\right)=25
Use the distributive property to multiply 3 by 1+4n.
3+12n-10n+6=25
Use the distributive property to multiply -2 by 5n-3.
3+2n+6=25
Combine 12n and -10n to get 2n.
9+2n=25
Add 3 and 6 to get 9.
2n=25-9
Subtract 9 from both sides.
2n=16
Subtract 9 from 25 to get 16.
n=\frac{16}{2}
Divide both sides by 2.
n=8
Divide 16 by 2 to get 8.
