begin{array c 3 x + 2 y = 6 5 x + 4 y = 8 endarray .

常见问题解答

• 使用替换法求解 $\{\begin{array}{c}3x+2y=6\\ 5x+4y=8\end{array}$

  

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

• 使用消元法求解 $\{\begin{array}{c}3x+2y=6\\ 5x+4y=8\end{array}$

  

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

• 使用 Gauss-Jordan 方法求解 $\{\begin{array}{c}3x+2y=6\\ 5x+4y=8\end{array}$

  

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

• 使用克莱默规则求解 $\{\begin{array}{c}3x+2y=6\\ 5x+4y=8\end{array}$

  

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