Question 224709
{{{16=3x+6x+7}}}


Step 1.  Combine like terms (x-terms in this case)


{{{16=(3+6)x+7}}}


{{{16=9x+7}}}


Step 2.  Subtract 7 from both sides of the equation


{{{16-7=9x+7-7}}}


{{{9=9x}}}


Step 3.  Divide by 9 to both sides of the equation


{{{9/9=9x/9}}}


{{{x=1}}}


Step 4.  ANSWER:  The solution is {{{x=1}}}.


I hope the above steps were helpful.
