Question

Can anyone demonstrate the workings to obtain the solution?

Answer 1

(E) `((14-7x)/(x^2-x))/((x-2)/(x-1))=-7/x`

Explanation:

`((14-7x)/(x^2-x))/((x-2)/(x-1))`

= `((7(2-x))/(x(x-1)))/((x-2)/(x-1))`

= `(-7(x-2))/(x(x-1))xx(x-1)/(x-2)`

= `(-7cancel((x-2)))/(xcancel((x-1)))xxcancel(x-1)/cancel(x-2)`

= `-7/x`
