In the left column: how was the numerical part of the answer found (addition, subtraction )
Setler79 [48]
You can find the numerical part of the answer because it is the same on the right side.

For example:
 ¹      <<==== Regrouped
  89
+
  67
---------
146   <<=== I had to press space so I could position it.

So that also happens in subtraction, the left side can be found by doing the same steps in the right column.
For example:

67
-                    <<=== this time there was no regrouping
12
-------
55

How do I solve the equation?
trapecia [35]

Answer:

(-3, 5) radius- r= 5

Step-by-step explanation:

x^2+6x+y^2-10y=-9

Rewrite ^2+6x+y^2-10y=-9 in the form of the standard circle equation

(x-(-3))^2+(y-5)^2= 5^2

Therefore the circle properties are:

(a, b)=(-3, 5), r= 5
