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

Short Answer

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