first combine lik terms so -6n+-10n=-16n
so the eqation would b
-16n+10≤-6 then try to get n by itself by subracting 10 from both sides so...
-16n+10≤-6
-10 -10
-16n≤-16 then divide by -16
-16n(/-1) ≤ -16(/-16)
(u have to switch the sign around when dividing by a negative nd a negative divided by a negative would b positive)
n is greater thanor equal to 1

-10n+10-6n⤠-6
minus 10 from both sides
-10n-6n⤠-16
do -10n-6n
-16n⤠-16
times eveything by -1 (sign changes round)
16n >= 16
divide both sides by 16
n>=1

-10n+10-6n<=-6
-16n+10<=-6
-16n+10-10<=-6-10
-16n<=-16
-16n/-16=>-16/-16
n=>1
