Question 131669
Step 1:  Remove parentheses by distributive property.
{{{11(3x+9)=104 }}}

{{{33x+99=104}}}


Step 2:  Get all variable terms on one side and number terms on the other.  That is, subtract 99 from each side.

{{{33x+99-99=104-99}}}
{{{33x=5}}}


Step 3:  Divide both sides by the coefficient of x.
{{{(33x)/33=5/33}}}
{{{x=5/33}}}
