I need to know how:

x-1.34)/X=.5851

x = 3.22969

How?
The X variable is givin. X = 3.22969
The form of this problem is an algebraic fraction.
To solve this issue , i chose the LCD method to clear
a fraction.

X -1.34 / X =.5851                   orig frac.

X /1 x (X-1.34 )/X = .5851X       mult by X /1

X^2 - 1.34X /X   = .5851X       solv- use cancela-
tion princ.

X - 1.34  = .5851X              result

Because the original algebraic fraction is now a
linear expression proves that the given X value
(3.22969) is correct.
THUS :
3.22969 -1.34 = .5851 x 3.22969
3.22969 - 1.34 = 1.88969
3.22969 x.5851 = 1.88969
