Question

How do you solve and graph `-9.1< d-6.3`?

Answer 1

See full explanation and graph below:

Explanation:

To solve you add `color(red)(6.3)` to each side of the inequality to isolate `x` and keep the inequality balanced:

`-9.1 + color(red)(6.3) < d - 6.3 + color(red)(6.3)`

`-2.8 < d - 0`

`-2.8 < d`

To solve in terms of `d` we reverse or "flip" the inequality:

graph{x > -2.8 [-10, 10, -5, 5]}
