Solve the System by the Substitution or Elimination Method $$\left( \begin{array} { l } x + y = - 5 \\x ^ { 2 } + 2 y ^ { 2 } - 7 y - 151 = 0\end{array} \right)$$

Short Answer

Solve the system by the substitution or elimination method. $$\left( \begin{array} { l } x + y = - 5 \\x ^ { 2 } + 2 y ^ { 2 } - 7 y - 151 = 0\end{array} \right)$$ Express your answer as an ordered pair. If there is more than one solution, separate your answers with a comma.
