9x= x+4
Subtract x on both sides to balance the equation.
8x= 4
Divide 8 into both sides. (the inverse of multiplication)
x= 1/2
We can check this by plugging in x.
9(.5)= .5+4
4.5= 4.5
I hope this helps!

Answer:
circle of radius 10 centered at (-2, 0)
Step-by-step explanation:
The equation is of the form ...
(x -h)^2 +(y -k)^2 = r^2
with (h, k) = (-2, 0) and r=10.
This is the standard form of the equation of a circle with radius r centered at (h, k).
See the attached for a graph.
