Question 404423
{{{1/3}}}x = 3x - 9 
Multiply both sides by 3 to get rid of the denominators
1x = 9x - 27
+27 = 9x - x
27 = 8x
x = {{{27/8}}}
x = 3{{{3/8}}} or 3.375

Check solution in original problem
{{{1/3}}}*{{{27/8}}} = 3x - 9
cancel 3 into 27
{{{9/8}}} = 3*{{{27/8}}} -9
{{{9/8}}} = {{{81/8}}} - 9
{{{9/8}}} = {{{81/8}}} - {{{72/8}}}; confirms our solution
