    do you mean 1/(x+4) - (1/x) = 1 ?

    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.

    well, it gets multiplied by the (x+4)(x) just like the left side.

    be careful with your parentheses, what you have there doesn't look quite right, but almost there

    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.
