Solve Simultaneously $\begin{aligned}& \frac{3 x}{7}+\frac{6 y}{11}=\frac{2}{21} \\& \frac{2 x}{5}-\frac{2 y}{3}=\frac{4}{3}\end{aligned}$

Short Answer

Solve simultaneously. Keep 3 significant digits in your final answers, but do not round until the end:
$\begin{aligned}& \frac{3 x}{7}+\frac{6 y}{11}=\frac{2}{21} \\& \frac{2 x}{5}-\frac{2 y}{3}=\frac{4}{3}\end{aligned}$
