Name: Anonymous 2009-08-31 7:24

1/x+ 6/x+7=0

how the fuck do I do this, seriously? I've done this problem fucking 3 times. the solution is -1 BUT I KEEP DOING THE WORK WRONG WHAT THE FUCK FUCK

Subtract seven, multiply by X. I seriously hope this is some kind of obscure troll.

x^-1 + 6x^-1 = -7
7x^-1 = -7

she can't write it out properly, it's:

1/x+ 6/(x+7)=0

Oh god, tell me you're 14. (facepalm.jpg)

Multiply by X to get rid of the fractions. Start there.

1/x + 6/(x+7) = 0
[(x+7) + 6x]/[x(x+7)] = 0
x + 7 + 6x = 0
7x = -7
x = -1

She?

Also what were the odds of the problem having the same solution regardless of those parentheses? It's crazy.

Well which one is it?

1/x + 6/(x+7) = 0
1/x = 6/(x+7)
x+7 = 6x
7 = 5x
x = 7/5

>>6, 7
Interesting, the answer is the same, regardless of interpretation.

i can't believe your incompetency
1/x and 6/x can be added since they share the denominator. so 7/x equals -7. then just divide it.
-1
my first time in this board and already...
