Hey there!
Firstly, we have to “add” the number “4” on each of your sides
Like: -2a -4 + 4> -8 +4
Cancel: -4 + 4 because it will give you “0”
Keep: -8+4 because it gives you “-4” and we have paid it off with -2a
Like: -2a>-4
Divide each of the sides by “-2”
Like: -2a/2 > -4/-2
Cancel: -2a/2 because it gives us “1”
Keep: -4/-2 because that’ll give us the answer on the left side of the inequality
So, a < 2 would be your answer
Good luck on your assignment and enjoy your day

Answer is t_<10
-3t+9_>-21
-3t_>-30
t_<10
**when you divide or multiply both sides by a negative you have to flip the sign**
you can substitute numbers to make sure your answer is correct. For example if u substitute t=9 -27+9_>-21 -18_>-21 which is correct.(but you’ll see it’ll be incorrect if u put t=11)
