Svp résoudre le système suivant: 5x+2y=16 3x-y=3

bonjour

5 x + 2 y = 16

3 x - y =  3

5 x + 2 y = 16

6 x - 2 y = 6

11 x = 22

x = 2

5 x + 2 y = 16

10 + 2 y = 16

2 y = 16 - 10

2 y = 6

y = 3

S ( 2 ; 3 )

Bonjour,

[tex]\left\{ \begin{array}{ll}

5x + 2y = 16\\

3x - y = 3

\end{array}

\right. 

[/tex]

[tex]\left\{\begin{array}{ll}

5x + 2y = 16\\

y = 3x - 3

\end{array}

\right. [/tex]

[tex]\left\{\begin{array}{ll}

5x + 2(3x - 3)= 16\\

y = 3x - 3

\end{array}

\right. [/tex]

[tex]\left\{\begin{array}{ll}

5x + 6x - 6 = 16\\

y = 3x - 3

\end{array}

\right. [/tex]

[tex]\left\{\begin{array}{ll}

11x = 22\\

y = 3x - 3

\end{array}

\right. [/tex]

[tex]\left\{\begin{array}{ll}

x = \frac{22}{11} \\

y = 3x - 3

\end{array}

\right. [/tex]

[tex]\left\{\begin{array}{ll}

x = 2\\

y = 3 \times 2 - 3

\end{array}

\right. [/tex]

[tex]\left\{\begin{array}{ll}

x = 2\\

y = 3

\end{array}
