Answer:

x=11

Step-by-step explanation:

3x+3(5x-6)= 180

Distribute 3 to 5x and -6

3x+15x-18=180

Combine like terms

18x-18=180

Add 18 to both side

18x=198

Divide 18 on both side

x=11

postnew [5]

The length is about 28 more than three times the width. Denoted as (a) width, and as (b) the length. Then move on to lay the system of equations, as done below:

$\begin{cases}2a+2b=136\\b=3a+28\end{cases}$
$\begin{cases}2a+2b=136|:2\\b=3a+28\end{cases}$
$\begin{cases}a+b=68\\b=3a+28\end{cases}$
$\begin{cases}a+3a+28=68\\b=3a+28\end{cases}$
$\begin{cases}4a=40|:4\\b=3a+28\end{cases}$
$\begin{cases}a=10\\b=3*10+28\end{cases}$
$\begin{cases}a=10\\b=58\end{cases}$
