do you mean 1/(x+4) - (1/x) = 1 ?
yes
ok for this type of equation, it's easiest to get rid of the fractions. so you want to multiply both sides by (x+4)(x) to get rid of both fractions on the left side.

Other answers:

what happens to the 1
well, it gets multiplied by the (x+4)(x) just like the left side.
oh ok
so can you move forward from there or are you still stuck?
I came up with x-x+4=x(x=4)
be careful with your parentheses, what you have there doesn't look quite right, but almost there
Ok thank you I'm going to see if i can go further
ok let me know if you need more help. remember when you are done you can always plug your answer back into the equation to see if it works.
