Solve the System by Using Either the Substitution Method or the Elimination-By-Addition

Short Answer

Solve the system by using either the substitution method or the elimination-by-addition method, whichever seems more appropriate. $$\left( \begin{array} { r l l } \frac { 1 } { 2 } x &-& \frac { 1 } { 6 } y &= & - 1 \\\frac { 1 } { 2 } x &+ &\frac { 1 } { 4 } y &= & - 11\end{array} \right)$$ If the equations of the system are dependent, or if a system is inconsistent, so indicate. In those cases enter dependent or inconsistent . Otherwise, enter your answer as an ordered pair ( x , y ).
