\textrm{Nem paralelo nem perpendicular}

Question 1

Resolva usando o método de substituição \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 2

Resolva usando o método de eliminação \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

Resolva usando o método de Gauss-Jordan \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

Resolva usando a regra de Cramer \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)
