Answer:

Step-by-step explanation:

$\sf Answer \begin{cases}\sf \rightarrowtail \:( 3x - 6) + (2x + 25) + (x + 11) = 180 \\ \sf \rightarrowtail \: 3x - 6 + 2x + 25 + x + 11 = 180 \\ \sf \rightarrowtail \: 3x + 2x + x - 6 + 25 + 11 = 180 \\ \sf \rightarrowtail \: 6x + 30 = 180 \\ \sf \rightarrowtail \: 6x = 180 - 30 \\ \sf \rightarrowtail \: 6x = 150 \\ \sf \rightarrowtail \: x = \frac{150}{6} \\ \sf \rightarrowtail \: x = 25\end{cases}$
