The first question you need to ask is..."What's the common denominator of the three fractions?"
%28x%2F2%29+-+%283x%2F12%29+=+%285%2F18%29 The common denominator is 36. Now you need the replace each fraction by its equivalent fraction with 36 as the denominator.
%28x%2F2%29%2818%2F18%29+=+%2818x%2F36%29
%283x%2F12%29%283%2F3%29+=+%289x%2F36%29
%285%2F18%29%282%2F2%29+=+%2810%2F36%29 Now rewrite the original equation using the equivalent fractions :
%2818x%2F36%29+-+%289x%2F36%29+=+%2810%2F36%29 Now if you multiply both sides by 36, you can clear the fractions.
36%28%2818x%2F36%29+-+%289x%2F36%29%29+=+%2836%29%2810%2F36%29 = 18x+-+9x+=+10
So:
9x+=+10
x+=+10%2F9
x+=+1.111...
