Question

4x + 2y = 3 = 3x - 7y

Answer 1

Respuesta:

4x + 2y = 3 = 3x - 7y

Explicación:

$\left \{ {{4X+2Y=3} \atop {3X-7Y=3}} \right.$

$\left \{ {{28X+14Y=21} \atop {3X-7Y=3}} \right.$

34X=27

X=$\frac{27}{34}$

4X$\frac{27}{34} +2Y=3$

Y=-$\frac{3}{34}\\ (X,Y)=\{\frac{27}{34},\frac{3}{34} ]$

$4X\frac{27}{34}+2X(-\frac{3}{34})=3=3X\frac{27}{34} -7X(-\frac{3}{34} )$

3=3=3

(X,Y)=$(\frac{27}{34},-\frac{3}{34})$
