Answer:

Hey there,

Let the unknown number be x

Here they say that ,

Seven more than twice a number,

2x + 7

Is greater than,

2x + 7 >

Negative 19,

2x + 7 > -19

Now solve for x

[tex]2x + 7 > - 19 \\ 2x > - 19 - 7 \\ 2x > - 26 \\ \frac{2x}{2} > \frac{ - 26}{2} \\ x > - 13[/tex]

So,

All the numbers which are greater than (-13) makes this statement true.

Examples

[tex]x = { - 12, - 11, - 10, - 9...} \\ [/tex]
