Question

Resuelve:

4x - 3y = 17
x- 6y = -1
__

2x - 5y = -21
-2x - 3y = -3

Answer 1

Explicación paso a paso:

A :

4x - 3y = 17

4x + 3y - 17 = 17 - 17

4x + 3y - 17 = 0

B:

X - 6y + 1 = -1 + 1

X - 6y + 1 = 0

C:

2x - 5y = -21

2x - 5y + 21 = - 21 + 21

2x - 5y + 21 = 0

D:

-2x - 3y + 3 = 0

Ahora cambias de signo:

-2x + 3y - 3=0
