Question

7x-15 y = 1
-X- 6 y = 8

Answer 1

• 7x-15y - 1 = 0
• x + 6y + 8 = 0

PROCEDIMIENTO:

7x-15y = 1

7x-15y - 1 = 1 - 1

7x-15y - 1 = 0

- x - 6y = 8

- x - 6y - 8 = 8 - 8

- x - 6y - 8 = 0

- 1 ( - x - 6y - 8 ) = - 1 . 0

- 1 . ( - x ) - 1 . ( - 6y ) - 1 . ( - 8 ) = 0

1x - 1 . ( - 6y ) - 1 . ( - 8 ) = 0

x - 1 . ( - 6y ) - 1 . ( - 8 ) = 0

x + 6y - 1 . ( - 8 ) = 0

x + 6y + 1 . 8 = 0

x + 6y + 8 = 0
