\frac{-130}{-5}>2n+5
Divide both sides by -5. Since -5 is negative, the inequality direction is changed.
26>2n+5
Divide -130 by -5 to get 26.
2n+5<26
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
2n<26-5
Subtract 5 from both sides.
2n<21
Subtract 5 from 26 to get 21.
n<\frac{21}{2}
Divide both sides by 2. Since 2 is positive, the inequality direction remains the same.
