2x/16 +30=-1/x How do i do this? help please :/

Question

hartnn · Answer

try multiplying 16x on both sides..that is to all terms....and simplify

anonymous · Answer

okay ill try that, thanks(:

anonymous · Answer

First you need to get all the Xs to one side:
-30-15 = x-2x

Then simplify:
-45 = -x

Since you have a negative on both sides, that will cancel out. Soooo:
x = 45

i got 8 and -8 for the awsner ????

phi · Answer

if you replace x with 8 in the equation, is the equation true, after simplifying?

anonymous · Answer

i tryed but then i got stuck

anonymous · Answer

x=-5,-3

phi · Answer

if the problem is 
$$ \frac{2x}{16}+30=\frac{-1}{x} $$
I would notice that
$$ \frac{\cancel{2}x}{\cancel{2}\cdot 8}+30=\frac{-1}{x} $$
to simplify it a bit

now multiply all the terms by 8x.  what do you get?  
(write out the whole equation)

phi · Answer

to multiply, just write 8x* in front of every term on both sides of the equal sign

anonymous · Answer

is it suppose to be a 16x instead of just 16
