Question 906699
You can first simplify the number on the right of the equality symbol, AND THEN SOLVE FOR x, if you want to know x; but the pre-simplification may be up to you:


{{{x/6=18/4}}}, your given
{{{x/6=(2*9)/(2*2)}}}
{{{x/6=9/2}}}
NOW you can multiply the left and right members by 6, and continue any simplifications.
{{{(x/6)6=(9/2)6}}}
{{{x=9*6/2}}}
{{{x=9*3}}}
{{{highlight(x=27)}}}


Know the properties of numbers, and TRUST them.  You will then usually have no doubts about your steps.  The properties will work; you just choose which ones to use as you find necessary from step to step.
