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. $$\left( \begin{array} { llll } 4 x &-& 7 y & = & 6 \\8 x &-& 14 y & =& - 5 \end{array} \right)$$ 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 ).
