Y-2>11 solve this inequality

Question

solve this inequality. graph and check your solution

Answer 1

Iquasia, this is solved just like there is an =.  Let's do an example.

 

y - 5 < 4.

 

Add 5 to both sides and get y < 9.

 

Now, to check your answer, let's pick a number less than 9, like 8.  8 - 5 < 4, right?

 

If we pick a number greater than 9, like 10, then 10 - 5 < 4 does not work, so we know that y < 9 is our answer.
