You can put this solution on YOUR website!
2/3 (x+9) = 1/3 (12-x)
\n" ); document.write( "2(x+9)/3 = (12-x)/3
\n" ); document.write( "(2x+18)/3 = (12-x)/3
\n" ); document.write( "with equal denominators we can delete them
\n" ); document.write( "2x+18=12-x --> x with x and single numbers together too
\n" ); document.write( "2x+x=12-18 --> calculate them
\n" ); document.write( "3x=-6 --> pass the number that is multiplying dividing
\n" ); document.write( "x=-6/3 and calculate
\n" ); document.write( "x=-2 \n" ); document.write( "

\n" );
