Question 79999
How would you do this kind of problem? Show step by step PLEASE! I get very confused with stuff like this... 
:
y  = {{{1/(2x)}}} + 5
:
Assume you want to find the value of x when y = 0 (x intercept)
:
{{{1/(2x)}}} + 5 = 0
:
Subtract 5 from both sides and you have:
{{{1/(2x)}}} =  -5
:
Multiply both sides by 2x and you have:
1 = -5(2x)
:
1 = -10x
:
x = -1/10
:
:
Check in original equation: x = -.1
{{{1/(2*-.1)}}} + 5 = 
{{{1/(-.2)}}} + 5
 -5 + 5 = 0

did this help?
