Question

Solve:
1/x+4-1/x=1
I found the lcd but lost afterwards.

Answer 1

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

Answer 2

yes

Answer 3

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.

Answer 4

what happens to the 1

Answer 5

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

Answer 6

oh ok

Answer 7

so can you move forward from there or are you still stuck?

Answer 8

I came up with x-x+4=x(x=4)

Answer 9

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

Answer 10

Ok thank you I'm going to see if i can go further

Answer 11

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.
