Hi,

 

I was struggling with binomials with fractional coefficients, e.g. x-1  _  x-1    =  -7

                                                                                                     3         2

Thanks

Idea - find LCD of denominators cheeky

 

 

6[\(\frac{x-1}{3}- \frac{x-1}{2} = -7 \)]

 

2x - 2 - 3x + 3 = -42

-x + 1 = -42                                        \(\left \{ 43 \right \}\)

      -1     -1

 

-x=-43

x = 43
