-28n-7+5\left(1+6n\right)=3n-5+8
Use the distributive property to multiply -7 by 4n+1.
-28n-7+5+30n=3n-5+8
Use the distributive property to multiply 5 by 1+6n.
-28n-2+30n=3n-5+8
Add -7 and 5 to get -2.
2n-2=3n-5+8
Combine -28n and 30n to get 2n.
2n-2=3n+3
Add -5 and 8 to get 3.
2n-2-3n=3
Subtract 3n from both sides.
-n-2=3
Combine 2n and -3n to get -n.
-n=3+2
Add 2 to both sides.
-n=5
Add 3 and 2 to get 5.
n=-5
Multiply both sides by -1.
