Question

ecuaciones lineales

1• 2x+7y=11



2• 3y +4y=11​

Answer 1

Respuesta:

1. $-\frac{2}{7}$
2. $y = \frac{11}{7}$

Explicación paso a paso:

$1) 2x + 7y = 11 :y = - \frac{2}{7}x + \frac{11}{7} \\\\-\frac{2}{7} x + \frac{11}{7} \\\\\frac{2}{7} x + \frac{11}{7} = -\frac{7x- 11 }{2} \\\\m = -\frac{2}{7} R// \\\\2) 3y + 4y \\3y + 4y = 7y \\7y = 11\\\\\frac{7y}{7} = \frac{11}{7} \\\\\frac{7y}{7} = y \\\\y = \frac{11}{7} R//$

Espero te ayude de algo suerte
