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

question 42

Short Answer

Solve each system by using either the substitution or the elimination-by-addition method, whichever seems more appropriate. $$\left( \begin{array} { c } \frac { 2 x } { 3 } - \frac { 3 y } { 4 } = 81 \\\frac { 11 x } { 6 } + \frac { y } { 5 } = 87\end{array} \right)$$
