Question

x+2y+9=0,3x+4y+17= simultaneous linear equations​

Answer 1

Step-by-step explanation:

X+2y+9=0 implies X+2y= -9 ________1

3x+4y+17=0 implies 3x+4y=-17________2

multiply equation 1 ×2 and subtract equation 2from equation 1

2x+4y=-18.

-3x-4y=17

-x=-1

implies X=1 . put X=1in equation 1

1+2y=-9

2y=-10

implies y=-10/2=-5
