ALGEBRA 2 Hard for idiots like me.

[From: ] [author: ] [Date: 11-12-13] [Hit: ]
These two are causing me trouble.What are we supposed to do?Take out absolute value bars,Divide both sides by 5 and u end up with -23/5. But since its an absolute value,Hope this helps!......
Inequalities: 5(6-4v)=v+21
with absolute values:.. l5b+9l + 16 = 2

These two are causing me trouble. What are we supposed to do? lol

-
The first one: 5(6-4v) = v+21

Multiply: 30 - 20v = v + 21

Subtract 30 from both sides and get: -20v = v - 9

Subtract v and get: -21v = -9

Divide both sides by -21 and then reduce ads get: 9/21 which reduces down to 3/7

The second problem: |5b + 9|+ 16 = 2

Subtract 16 from both sides to get |5b+9| = -14

Take out absolute value bars, get 5b+9 = -14

Subtract 9 and get 5b = -23

Divide both sides by 5 and u end up with -23/5. But since it's an absolute value, it changes to POSITIVE 23/5

Hope this helps! (I hate algebra 2 too lol boring class but I'm glad I could help ya out)
