Question

$$p ( x ) = 3 x + 1 , x = - \frac { 1 } { 3 }$$

Answer

p=-31;x=-1/34

Solution


Substitute \(x=-\frac{1}{34}\) into \(px=3x+1\).
\[-\frac{p}{34}=\frac{31}{34}\]
Solve for \(p\) in \(-\frac{p}{34}=\frac{31}{34}\).
\[p=-31\]
Therefore,
\[\begin{aligned}&p=-31\\&x=-\frac{1}{34}\end{aligned}\]
