Split this:

\(8<4x+4, 4x+4<2x+20\)

\(4x+4<2x+20, 2x<16, x<8\)

Combining \(1 and \(x<8\) we get

\(1

You are very welcome!

Edit:

The LaTex is not displaying properly - I do not know whay, maybe it will fix itself

The final answer was 1

\( 8 < 4x + 4 < 2(x + 10)\\ 8 < 4x + 4 \quad and \quad 4x + 4 < 2(x + 10)\\ 4 < 4x \qquad and \qquad 4x + 4 < 2x + 20\\ 1 < x \qquad \;\;and \qquad \;\;\quad2x < 16\\ 1 < x \qquad \;\;and \qquad \;\;\quad x < 8\\~\\ 1
