Solve using the substitution method of \left\{ \begin{array} { c } { 3 x + 2 y = 6 } \\ { 5 x + 4 y = 8 } \end{array} \right.

\left(x,y\right) = \left(4,-3\right)

Solve using the elimination method of \left\{ \begin{array} { c } { 3 x + 2 y = 6 } \\ { 5 x + 4 y = 8 } \end{array} \right.

\left(x,y\right) = \left(4,-3\right)

\left(x,y\right) = \left(4,-3\right)

\left(x,y\right) = \left(4,-3\right)

Solve using the substitution method of $\left\{ \begin{array} { c } { 3 x + 2 y = 6 } \\ { 5 x + 4 y = 8 } \end{array} \right.$

$(x, y) = (4, - 3)$
Solve using the elimination method of $\left\{ \begin{array} { c } { 3 x + 2 y = 6 } \\ { 5 x + 4 y = 8 } \end{array} \right.$

$(x, y) = (4, - 3)$
Solve using the Gauss-Jordan method of $\left\{ \begin{array} { c } { 3 x + 2 y = 6 } \\ { 5 x + 4 y = 8 } \end{array} \right.$

$(x, y) = (4, - 3)$
Solve using the Cramer's rule of $\left\{ \begin{array} { c } { 3 x + 2 y = 6 } \\ { 5 x + 4 y = 8 } \end{array} \right.$

$(x, y) = (4, - 3)$
