Answer:
b
Step-by-step explanation:
I have done what you want
1st
6x+9y=0
9y=6x
Y=6x/9
2nd
6x+9y =0
6x=9y
X=9y/6 ans
You need to add a -1
We can find this by setting up the equation like so
x + (-6) + 12 + 15 / 4 = 5
x + 21 = 20
x = 20 -21
x = -1
Now if we insert -1 where x is located in the equation, you will get a means of 5
The answer is A I suppose
