-2a - 4 > -8
add 4 to both sides

-2a - 4 + 4 > -8 + 4
-2a > -4

divide both sides by -2 AND change the direction of the sign because we're dividing by a negative

a < 2

ANSWER: a < 2

Hope this helps! :)

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
