Question #7b60e

Answer 1

`x > - 2`; `x in ZZ`

Explanation:

We have: `4 x + 3 < 6 x + 7`; `x in ZZ`

Subtracting `7` from both sides of the inequality:

`Rightarrow 4 x - 4 < 6 x`

Subtracting `4 x` from both sides:

`Rightarrow - 4 < 2 x`

Dividing through by `2`:

`Rightarrow - 2 < x`

`therefore x > - 2`
