Accepted Answer

\left(x,y\right) = \left(\frac{46}{7},\frac{36}{7}\right)

Question 2

使用消元法求解 \left\{ \begin{array}{l}x\div 2+y\div 3=5\x-y\div 2=4\end{array}ight.

Accepted Answer

\left(x,y\right) = \left(\frac{46}{7},\frac{36}{7}\right)

Question 3

使用 Gauss-Jordan 方法求解 \left\{ \begin{array}{l}x\div 2+y\div 3=5\x-y\div 2=4\end{array}ight.

Accepted Answer

\left(x,y\right) = \left(\frac{46}{7},\frac{36}{7}\right)

Question 4

使用克莱默规则求解 \left\{ \begin{array}{l}x\div 2+y\div 3=5\x-y\div 2=4\end{array}ight.

Accepted Answer

\left(x,y\right) = \left(\frac{46}{7},\frac{36}{7}\right)
