#### Answer

$\left( -\infty,\infty \right)$

#### Work Step by Step

$\bf{\text{Solution Outline:}}$
To solve the given inequality, $
7(4-x)+5x\lt2(16-x)
,$ use the Distributive Property and the properties of inequality.
For the interval notation, use a parenthesis for the symbols $\lt$ or $\gt.$ Use a bracket for the symbols $\le$ or $\ge.$
For graphing inequalities, use a hollowed dot for the symbols $\lt$ or $\gt.$ Use a solid dot for the symbols $\le$ or $\ge.$
$\bf{\text{Solution Details:}}$
Using the Distributive Property and the properties of inequality, the inequality above is equivalent to
\begin{array}{l}\require{cancel}
7(4)+7(-x)+5x\lt2(16)+2(-x)
\\\\
28-7x+5x\lt32-2x
\\\\
-7x+5x+2x\lt32-28
\\\\
0\lt4
\text{ (TRUE)}
.\end{array}
Since the solution above ended with a TRUE statement, then the solution set is the set of all real numbers. In interval notation, the solution set is $
\left( -\infty,\infty \right)
.$
The graph of the solution set is the number line itself.
