Well, darling, solving X squared plus Y squared equals 5 is as easy as pie. It's simply the equation of a circle with a radius of square root of 5. So, if you're looking for the solutions, just plug in some values for X and Y that satisfy the equation and you're good to go. Math can be a piece of cake if you know where to look!
Oh, dude, it's like a classic case of the Pythagorean theorem. So, to solve for x and y, you just need to realize that this equation represents a circle with a radius of sqrt(5). You can find all the possible x and y values that satisfy the equation by plugging in different values for x or y and solving for the other variable. Easy peasy, right?
x2+y2=5 can be solved as follows:
is you're solving for x...
take the square root of both sides:
√x2+√y2=√5 which gives you x+y=√5
subtract y to isolate x:
x= -y+√5 or x=√5-y
OR, to solve for y…take the square root of both sides:
√x2+√y2=√5 which gives you x+y=√5
subtract x to isolate y:
y=√5-x or y= -x+√5
=====================================
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 = 5 ... the graph is
a circle, with its center at the origin, and with a radius of sqrt(5). 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".
