{2x+3y=7
{3x-y=5

Answer 1

$\large\bm{\begin{cases}2x + 3y = 7 \\ 3x - y = 5\end{cases}} \\ \\ \large\bm{\begin{cases}2x + 2y = 7 \\ y = - 5 + 3x\end{cases}} \\ \\\large\bm{} 2x + 2\left( - 5 + 3x\right) = 7 \\ \\ \large\bm{}x = \dfrac{17}{8} \\ \\ \large\bm{}y = - 5 + 3 \times \dfrac{17}{8} \\ \\\large\bm{}y = \dfrac{11}{8} \\ \\ \bm{\large\boxed{\boxed{  { \large \bm{ \left(x,y\right) =\left( \dfrac{17}{8} , \dfrac{11}{8} \right) }}}}}$
