Question

prove: [(3x+2)/x+1]-5/6=0

Answer 1

[(3x+2)/x+1]=5/6
3x+2=5x+5/6
6/6(3x+2)=(5x+5)/6
(18x+12)/6=(5x+5)/6
(13x+7)/6=0
13x=-7 x=-7/13
[[3(-7/13)+2]/[(-7/13)+1]-(5/6)=0

Answer 2

I dropped that negative sign in the next to last step... Needless to say that problem took a lot longer than it should have...

Answer 3

thanks so much

Answer 4

oh my i've typed it wrong. it's supposed to be x-1... :(
[(3x+2)/x-1]-5/6=0

Answer 5

how is it now? please help me..

Answer 6

[(3x+2)/x-1]=5/6
3x+2=5x-5/6
6/6(3x+2)=(5x-5)/6
(18x+12)/6=(5x-5)/6
(13x+17)/6=0
13x=-17 x=-17/13
[[3(-17/13)+2]/[(-17/13)+1]-(5/6)=0
