Solve the system of equations by the substitution method: \( \left\{\begin{array}{l}\frac{1}{3} x-y=2 \\ x-3 y=6\end{array}\right. \) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The solution is \( \square \). There are infinitely many solutions; \( \left\{(x, y) \left\lvert\, \frac{1}{3} x-y=2\right.\right\} \) or \( \{(x, y) \mid x-3 y=6\} \). C. There is no solution; \( \} \) or \( \varnothing \).

In the expansion \( (x+y)^{10} \), what is the coefficient of the \( x^{4} y^{6} \) term?
