For each expression, simplify if possible. If applicable, click on "Cannot be simplified". \( \frac{6 y+5}{5 y+6}=\square \)

1. Rortanto, \( \frac{3}{5}+\frac{1}{2} \times\left(\frac{3}{8}-\frac{3}{12}\right) \)

\begin{tabular}{|l|l|}\hline\( \quad \frac{\square}{9}=1 \) & (b) \( \quad \frac{3}{\square}=3 \) \\ \hline\end{tabular}

g) \( \frac{x}{7}+\frac{4}{7}+\frac{x}{2}-\frac{1}{2}+4=7 \)

Qual a classificação do sistema abouxa? \[ \begin{aligned} x+y & =2 \\ 3 y & =9\end{aligned} \]

\( 8 y+4 \) for \( y=7 \)
