Let x = the dealer's cost, then:
\n" ); document.write( "\"x%2B0.3x+=+5200\" Factor an x from the left side.
\n" ); document.write( "\"x%281.3%29+=+5200\" Divide both sides by 1.3
\n" ); document.write( "\"x+=+4000\"
\n" ); document.write( "The dealer paid $4,000.00 for the car.
\n" ); document.write( "
\n" );
