add 2n to both sides to get
10n -10 < 6
then add 10 to both sides to get
10n < 16
then divide both sides by 10
to get
n < 1.6

8n - 10 < 6 - 2n Add 2n to both sides...
10n - 10 < 6 Add 10 to both sides...
10n < 16 Divide both sides by 10...
n < 16/10 = 8/5

really simple first get the n to just one side
8n-10<6-2n
+2n +2n
to get 10n -10 <6
then get the numbers to just one side
10n-10<6
+10 +10
to get 10n<16
now you just need n by its self so divide the 16 by ten and you have your answer (1.6)
The only time the sign might change is when you divide by a neggitve number then you filp the sign.

8n-10<6-2n
add 2n to each side
10n-10<6
Add 10 to each side
10n<16
divide each side by 10
n<1.6

First you need to place the N terms on the same side and the constants on the same side so
10n < 16
now solve for n
n< 16/10
