The price of 8 citrons and 3 fragrant wood apples is 84 units. The price of 3 citrons and 8 fragrant wood apples is 59 units. Find the price of a citron and the price of a wood apple.

e. \( 2 x^{2}+7 x=4 \)

suelve la siguiente ecuación: \[ 40+2,5 \bullet x=100 \] Luál es el valor de \( x \) ? \( \begin{array}{llll}56 & \text { B) } 40 & \text { C) } 24 & \text { D) } 16\end{array} \)

\begin{tabular}{l} 25. \begin{tabular}{l}\( -6 x+4 y \geq 8 \) \\ \( y<-x-1 \) \\ \begin{tabular}{|l|l|l|l|}\hline \\ \hline & \\ \hline\end{tabular} \\ \hline \\ \hline\end{tabular} \\ \hline\end{tabular}

Solve for \( x \) if \( x=\sqrt{x+\sqrt{x+\sqrt{x+\sqrt{x+\sqrt{x+\ldots}}}}} \)

\( ( 15 x - 12 ) ^ { \circ } + 5 x - 18 = 180 \)
