Question

6x + 3y = 18
-2x + 2y = 6
solución urgenteeeee​

Answer 1

Respuesta:

"x" vale 1 e "y " vale 4.

Explicación paso a paso:

$\left \{ {{6x + 3y=18} \atop {-2x + 2y=6\\}} \right.$

⇒×3  = $-6x + 6y=18$

$\left \{ {{6x+3y=18} \atop {-6x+6y=18}} \right$  ⇒ $\left \ {{9y=36}$

y = 4

$-2x + 2(4) = 6\\-2x + 8 =6\\-2x=-2\\x=1$
