Question

(ii) 9x + 3y +12=0
18x+6y +24=0​

Answer 1

Step-by-step explanation:

9x+3y+12=0 ×4 eq1

18x6y+24=0 × 2 eq2

squareing both sides

36x+ 12y= 36

36x+12y= 48

0 24y =12

y= 24÷12 =12

y=12

putting the value ep 1

9x+3y+12=0

9x+3y =12

9x+3(12) =12

9x+ 36 =12

x = 36 =12-9

x= 36 = 3

3x = 36

x =36÷3= 12

x= 12

y= 12

x=12
