Question 10535
The first question you need to ask is..."What's the common denominator of the three fractions?"

{{{(x/2) - (3x/12) = (5/18)}}} The common denominator is 36. Now you need the replace each fraction by its equivalent fraction with 36 as the denominator.

{{{(x/2)(18/18) = (18x/36)}}}
{{{(3x/12)(3/3) = (9x/36)}}}
{{{(5/18)(2/2) = (10/36)}}} Now rewrite the original equation using the equivalent fractions :

{{{(18x/36) - (9x/36) = (10/36)}}} Now if you multiply both sides by 36, you can clear the fractions.

{{{36((18x/36) - (9x/36)) = (36)(10/36)}}} = {{{18x - 9x = 10}}}

So:
 {{{9x = 10}}}
{{{x = 10/9}}}
{{{x = 1.111}}}...
