Question

metodo por igualacion
{3x+7y=17
2×+5y=12​

Answer 1

Respuesta:

​$\left \{ {{3x + 7y=17} \atop {x + 5y=12}} \right.$

$\left \{ {{3x + 7y=17} \atop {x=12 - 5y}} \right.$

3(12 - 5y) + 7y= 17

y= $\frac{19}{8}$

x= 12 - 5 x $\frac{19}{8}$

x= $\frac{1}{8}$

• entonces :v

x= $\frac{1}{8}$

y= $\frac{19}{8}$
