kwik-kid Posted March 19, 2011 Share Posted March 19, 2011 when rearanging a fraction liek that, i always eliminate the fraction, in this case it would be to times by (6 + 5d) so it will be "c(6+5d) = 9d-2 exapand the left side and re arrange... if you are left with more than one D, you can factorise it out so your left with just d(something) = something, then divide by the something in the bracket...
