Step 1

We first get rid of the absolute sign

9<4x+7 or, -9>4x+7

Step 2

Then we find x from each

9<4x+7

9-7<4x

2<4x

$\frac{2}{4}<x$

$\frac{1}{2}<x$

-9>4x+7

-9-7>4x

-16>4x

-4>x

Answer:$\frac{1}{2}<x\text{}{\textstyle \phantom{\rule{1em}{0ex}}}\text{or}{\textstyle \phantom{\rule{1em}{0ex}}}\text{}-4x$
