Question

2x + 7 < 1 How can I solve x in this inequality?

Answer 1

`x=ZZ^-` which is less than `-4`

Explanation:

For any non-negative integer, only 0 is less than 1. But it is impossible to make `2x+7` less than 1 without making `x` a negative number.
(it is going to be too complex with all possible number values of x so we will assume that `x` is an integer, which means that it is a number like 1,2,3,4, or 0,-1,-2,-3,-4 and so on)
the biggest integer value of `x` which can make `2x+7` less than 1 is `-4`
`x` thus is a negative integer which is equal to or less than `-4`
