Let f(x) = 4x-5 and g(x) = 3x, find (f/g)(x).

(f/g)(x) = f(x)/g(x) = (4x - 5) / 3x

 

If it needs to be simplified then:

 

(4/3)x - 5 / 3x

[  4x-5] / [ 3x], solve for x

 

Solve for x:
(4 x-5)/(3 x) = 0

Multiply both sides by 3:
(4 x-5)/x = 0

Multiply both sides by x:
4 x-5 = 0

Add 5 to both sides:
4 x = 5

Divide both sides by 4:
Answer: |x = 5/4

(f /g)(x)   =  f(x)  / g(x)    = [ 4x - 5 ] / [3x]    =  [4x] / [3x]   -   5 /[3x]    =    (4/3) - ( [5] / [3x] )
