Can you please see if you got the same answer as I did? Thank you.

3/x + 2/x-4

3x-12=2x

subtract 3x from both sides you get -12=-1x divide by -1 final answer is 12.

yes, the solution to 3x-12=2x

is x = 12

but ...

how did 3/x + 2/x-4

magically turn into the equation

3x-12=2x ????

I multiplied each fraction by (x)(x-4)

you must have had

3/x = 2(x-4)

cross-multiplying would have given you

3x - 12 = 2x

ok, looks like a simple typo.

3/x+ 2/x-4 = 3(x-4)+ 2(x)=0

3x-12+2x=0

3x+2x=12

5x=12

x=12-5

x=7

or only if you cross multiply the 3*x-4 which is 3x-12 and put it equal to 2*x which is 2x that could work.
