A=v^2/r solve for v, solve for r

To rearrange these for v and r we must use BEDMAS.

First, times both sides by r, getting Ar = v²r/r
You can cancel out r/r to get Ar = v²

To get v, square root both sides. √Ar = √v²
Cancel out the square root and the squared v = √Ar

To get r, go back to Ar = v², then divide both sides by A. rA/A = v²/A
Then cancel out A/A to get r. r = v²/A

If one were to put the y value into the equation, they could find out what x is for a certain value of y.  putting in the value of y (1), we get the equation: 1=4x-12=4xx=0.5this means that the value of x when why is 1 is x=0.5
