Question

How do you solve the inequality `7 + x + 10 < -2`?

Answer 1

`x<-19`.

Explanation:

We start with:
`7+x+10<-2`.
`7` and `10` can be added. So,
`x+17<-2`.
Like we would do in normal algebra, we pass `+17` to the right, so,
`x<-2-17`,
`x<-19`.
We do not change the `<` sign in any moment because `x` doesn't change sign.

Hope it Helps! :D .
