Answer:
Step-by-step explanation:
A quadratic equation has one root if the discriminant is 0.
That is we need for this particular question.
Compare the following to find :
The variable is representative of the variable here.

Sure! I'm glad you reached out for help, because it's better to understand a topic than just asking for someone to solve it for you.
Actually, this is incorrect.
2x-3y=-24 would be simplified like this:
2x/2-3y=-24/2 making
x-3y=-12
Divide by negative 3
x-3y/-3=-12/-3
x+y=4
I'm not sure how your textbook got from 2x-3y=-24 to x+6y=18, but I don't think that's correct. Mainly because x+6y=18 would be simplified to x+y=3 which is different from the answer shown above.
I'm really sorry I couldn't help, maybe I misread something? Maybe something was mentioned that I couldn't see in the picture?
