We can readily know the x^2-4x+4=3y then use it to replace the same function in the first equation which refers to the 3y+y^2-6y=0
y^2-3y=0
y(y-3)=0
y1=0 -----------y2=3
It’s already in ascending order.
3/5= .6
5/8= .625
5/6= .833
7/4= 1.75
Answer:
9x over 2 plus 60 if that's an option
First get all the terms on the same side:

Now solve using the quadratic formula which is:

Plug in the values:

So the answer is:
