Step-by-sep explanation:
Given:
Diameter of circle = 20 units
Center of circle = (-1, 7)
Standard form of the equation of a circle is expressed in the center-radius form as:
,
Where,
h = -1
k = 7
r = ½ of diameter = ½(20) = 10 units
Plug in the values into the equation



Answer: See below
Step-by-step explanation:
Isolate x for x-2y+2z=9
3x=9+2y
....(1)
Substitute (1) into the 2nd equation


7y=-3
y=-3/7
Substitute y=-3/7


Isolate z by substituting it



For x =9+2y/3 substitute z=59/21 and y=-3/7
