x=0 and y=4 or;

x=0 and y=-4 or;

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".

How do you solve 0 equals x squared minus ten x plus 16?

x^(2) - 10x + 16 = 0 Factors of '16', which are, 1,2,4,8,16. Select two numbers from this list that add/subtract to '10' . They are '2' and '8'. Setting up brackets ( x 2)(x 8) Since '16' is positive(+), then both signs must be the same. Since '10x' is negative (-) , then both signs are negative. Hence (x - 2)(x - 8 ) = 0 When x - 2 = 0 x = 2 & when x - 8 = 0 x = 8 So the two answers are ,2, & ,8, .

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.
