6n+30<34+8n
Use the distributive property to multiply 6 by n+5.
6n+30-8n<34
Subtract 8n from both sides.
-2n+30<34
Combine 6n and -8n to get -2n.
-2n<34-30
Subtract 30 from both sides.
-2n<4
Subtract 30 from 34 to get 4.
n>\frac{4}{-2}
Divide both sides by -2. Since -2 is negative, the inequality direction is changed.
n>-2
Divide 4 by -2 to get -2.
