Question

x+2y+9=0,3x+4y+17=0 in elimination method​

Answer 1

x + 2y = -9 | 3x + 6y = -27

3x + 4y = -17

3x + 6y = -27

___________

- - +

____________

-2y= 10

y = -5

x = 1

Answer 2

Step-by-step explanation:

$x + 2y = - 9 \: \: \: \: \: 3x + 4y = - 17$

MULTIPLYING FIRST EQN. WITH 3 AND THEN SUBTRACTING IT WITH SECOND EQN.,

$4y - 6y = - 17 + 9$

$- 2y = - 8$

$y = 4$

APPLYING IT IN THE EQN. ,

$x + 8 = - 9$

$x = - 17$

X=-17. AND Y=4
