Answer 1

Respuesta:

7x+8y=−8

7x+8y+−8y=−8+−8y

7x=−8y−8

$\frac{7x}{7} = \frac{-8y-8}{7}\\ \\ x= \frac{-8}{7}y+\frac{-8}{7}$

--------------------------------------------------------------------

7x+6y=8

7x+6y+−6y=8+−6y

7x=−6y+8

$\frac{7x}{7} = \frac{-6y+8}{7}\\ \\x= \frac{-6}{7}y +\frac{8}{7}$
