Question 343751: I am trying to figure the following problem out for work. x-7.70/x=.47 i would like to know how the solution will work. Can you help with this? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! x-7.70/x=.47
----
Multiply thru by x to get:
x^2-7.70 = 0.47x
---
Rearrange:
x^2-0.47x - 7.70 = 0
----
Solve using the Quadratic formula:
x = [0.47 +- sqrt(0.47^2 -4*1*-7.4)]/2
----
x = [0.47 +- sqrt(29.8209)]/2
----
x = [0.47 + 5.4609]/2 or x = [0.47-5.4609]/2
----
x = 2.9654 or x = -2.4955
