x=4 and y=0 or;
x=-4 and y=0 all are solutions
=========================================
First, you need to understand clearly what "solve" means.
The "solution" to an equation normally means a set of numerical values for all
of the variables that appear in it, that makes the equation a true statement.
In order to find a solution, you generally need the same number of different
equations as there are variables in them. That is, if the equation has both
'x' and 'y' in it, then you need two different facts about their relationship in
order to figure out what numbers they are.
When you graph the equation in the question ... x2+ y2 = 16 ... the graph is
a circle, with its center at the origin, and with a radius of 4. Every point on that
circle has 'x' and 'y' coordinates, and every point is a solution to the equation.
So, just as it stands, there are an infinite number of "solutions".

10 squared plus x equals 26 squared?
16
30 squared plus 16 squared equals x squared?
30 squared is 900. 16 squared 256. add them and you get 1156. Now, simply do: √1156 The answer is 34. Its simple: (30•30)+(16•16)=x^2 900+256=x^2 1156=x^2 √1156=x 34=x
How do you factor 2x squared -12x plus 16 equals 0?
2(x - 2)(x - 4)
X squared plus y squared plus z if x equals 7 y equals 6 and z equals 4?

How do you solve 0 equals x squared minus ten x plus 16?
Solve using the quadratic formula
10 squared plus x equals 26 squared?
16
X2 plus 8x plus 16 equals?
(x + 4)(x +4) or (x + 4)squared
30 squared plus 16 squared equals x squared?
30 squared is 900. 16 squared 256. add them and you get 1156. Now, simply do: √1156 The answer is 34. Its simple: (30•30)+(16•16)=x^2 900+256=x^2 1156=x^2 √1156=x 34=x
X squared plus 9 squared equals 12 squared?
X = √63
How do you factor 2x squared -12x plus 16 equals 0?
2(x - 2)(x - 4)
X squared plus y squared plus z if x equals 7 y equals 6 and z equals 4?
89
How do you graph the equation x squared plus y squared equals 16?
You are describing a circle, with its center at the origin and a radius of 4 (the square root of 16)
How do you solve 0 equals x squared minus ten x plus 16?
Solve using the quadratic formula
3 squared plus x equals 25 solve x?
32 + x = 259 + x = 25x = 25 - 9x = 16
What is the solution set for the equation x squared minus 6x plus 9 equals 16?
{-1,7}
IF 2 plus 3 equals 10. 7 plus 2 equals 63. 6 plus 5 equals 66. 8 plus 4 equals 96 therefore 9 plus 7 equals?
2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.
If x equals 4 and y equals 4 x squared plus y squared is how much?
x2 (4x4=16) + Y2 (4x4=16) = 32 You normally would leave out the bracketed bits but to simplify the equation. Cheers.
