The above answer is wrong. (84000-45000) is not 28000, it is 39,000. Therefore 39000/3 is 13000. M =13000.

i tried and tried and i cant find the answer. is it not a solution. (3/x)-1=7/(x-20)

*November 23, 2009*

**college math**

it suppose to be (3/x)-1=7/(x-20)

*November 23, 2009*

**college math**

i wrote it wrong the 1st time. this is the problem. solve: (3/x)-1=(7/x-20)

*November 23, 2009*

**college math**

solve: (3/x)/1=(7/x-20) i keep getting different answers for this question. the last answer i got was 20 (which would make it not a solution) but im not sure if that is right
