Question

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

Answer 1

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

Answer 2

(3/x)-1=(7/x-20)
why are there brackets around the right side? Did you mean 7/(x-20) ?
I can only take your question at face value the way you typed it.
Then it would be the same as

3/x - 1 = 7/x - 20

multiply each term by x

3 - x = 7 - 20x
19x = 4
x = 4/19

Answer 3

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