Question 1021448
13/(3x-9)=2/(6-x)
13/3(x-3)=2/(6-x)
13*(6-x) is top left times bottom right.  It is 78-13x
3(x-3)*2, or (3x-9)*2)=6x-18 bottom left times top right
6x-18=78-13x
19x=96
x=(96/19)
---------------------
13/(288/19)-171/19)=2/(114-19)-96/19, to use common denominator of 19
13/(117/19)=2/(18/19)
divide by a fraction, invert and multiply
13*19/117 should equal 38/18
247/117 should equal 19/9
divide top and bottom of 247/117 and get 19/9, checks
