do u know 5x+12=3x-6
\n" ); document.write( "5x+12=3x-6
\n" ); document.write( "5x-3x+12=3x-3x-6
\n" ); document.write( "2x+12=0-6
\n" ); document.write( "2x+12=-6
\n" ); document.write( "2x+12-12=-6-12
\n" ); document.write( "2x+0=-18
\n" ); document.write( "2x=-18
\n" ); document.write( "2x/2=-18/2
\n" ); document.write( " $\"highlight%28x=-9%29\"$
\n" ); document.write( "Check by letting x=-9 and see if both sides =.
\n" ); document.write( " $\"5%28-9%29%2B12=3%28-9%29-6\"$
\n" ); document.write( " $\"-45%2B12=-27-6\"$
\n" ); document.write( " $\"-33=-33\"$ We're right!
