Question

equation 9 X + 3 y + 12 =

0 and 18 x + 6 y + 24 = 0​

Answer 1

Answer:

9x=-12-3y x=(-12-3y)/9

18x+6y+24=0

18 (-12-3y)+6y+24=0

-216-54y+6y+24=0

-192-48y=0

-48y=192

y=-192/48=-4

so y=-4

then,

x=(-12-3y)/9=[-12-(3x-4)]/12=(-12+12)/

12=0/12=0

so x=0 ; y= -4

Hope its helpful!!! plz mark it as brainliest!!!!
