Help!!! Can't find the answer!

Question

3(d-1)>-4

Answer 1

First, you want to treat inequalities exactly like you would a normal equation. There is one *major* exception, though - every time you multiply or divide across the inequality with a negative number, you need to change the direction of the inequality.

 

So, first, we divide both sides by 3 to get

 

(d - 1) > -4/3

 

Now, add 1 to each side

 

d > -4/3 + 1 

d > -1/3

 

We did not have to use the special rule about the negative numbers here, but it is good to keep in your mind.

 

I hope this helps!
