Question

How do you solve and graph `b – 4 < 2.5`?

Answer 1

`b < 6.5`
Draw a number line and mark everything to the left of `6.5` as included in the solution set.

Explanation:

Given `b-4 < 2.5`

You can add the same amount to both sides of an inequality without effecting the orientation of the inequality.

So, by adding `4` to both sides we get
`color(white)("XXXX")` `b < 6.5`
