Please help me solve x-6 = 2 + (x+1)/(x+4) for x

[fcbsoccer23]

x-6 = 2 + (x+1)/(x+4)

and in this problem

14-x = (x-6)/(x-3)

Thanks.

Re: Help me solve for x!

x-6 = 2 + (x+1)/(x+4)

start by multiplying every term by (x+4) ...

(x-6)(x+4) = 2(x+4) + (x+1) ... now solve for x.

and in this problem

14-x = (x-6)/(x-3)

multiply both sides by (x-3), then solve for x

Thanks.

i need an actual answer because i get stuck with a quadratic formula that doesn't give me an answer it just says nonreal numbers or some really random numbers that go on forever. please someone finish those problems.

Why don't you show us what your work is so that we can help you figure out what you're doing wrong.

Dear fcbsoccer23,

You're on the right track if you're thinking of using the quadratic formula. Let's see what you've done so far so we can diagnose where you're getting stuck. It's true, if you turn your answer's into decimals, they will be irrational. The decimal places will not terminate nor repeat. It's a better exercise if you don't turn your answers into decimals for these problems.

Don't let that scare you.
If your quadratic ends up having (as example) sqrt(112), then all you need to do is simplify (if possible):
sqrt(112) = sqrt(16 * 7) = 4sqrt(7) ; simply leave answer in that format; kapish?

It's NOBODY's fault if sqrt(7) is not a nice integer!
