Is x-1 = 3-4x/x-2
this:
x-1 = (3-4x)/(x-2)
or
x-1 = 3-(4x/x)-2
or
x-1 = 3-(4x)/(x-2)?

It looks like I see a fraction in there. First get rid of the fraction by multiplying x/1. Then you will have x-1 = 3-4x -2. Then you treat as an equation. Combine terms x-1= 1-4x.. Add 4x to both sides and you will have 5x -1=1.. Add 1 to both sides to isolate 5x. Then you will have 5x=2. Divide 5x on both sides and you will have 2/5 as your answer.

[x-1][x-2]=3-4x upon multiplication by x-2.
xx-3x+2=3-4x
xx+x-1=0
x=-0.5+/-0.5sqrt[5]

(x - 1).(x - 2) = 3 - 4x
x² - 3x + 2 = 3 - 4x
x² + x - 1 = 0
x = [ - 1 ± â(1 + 4) ] / 2
x = [- 1 ± â(5)] / 2
x = 0.618, x = - 1.62
