13.20 minus blank = 9.66
\n" ); document.write( "13.20-x=9.66 [solve for x]
\n" ); document.write( "13.20-13.20-x=9.66-13.20 [Subtract 13.20 from both sides to isolate the x]
\n" ); document.write( "-x=-3.54
\n" ); document.write( "-x/-1=-3.54/-1 [Multiply each side by (-1) to isolate the x]
\n" ); document.write( "x=3.54
\n" ); document.write( ".
\n" ); document.write( "Check by plugging (x=3.54) back into the original equation:
\n" ); document.write( "13.20-(3.54)=9.66
\n" ); document.write( "9.66=9.66 [Checks out]
\n" ); document.write( "
\n" );
