ok, first for the easier part:
\n" ); document.write( "2x-3=7
\n" ); document.write( "2x = 10
\n" ); document.write( "x = 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this solution is seen on the graph of y=2x-3 and y=7... they intersect at x=5, as shown: \"graph%28200%2C200%2C-10%2C10%2C-25%2C25%2C2x-3%2C+7%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now the action of the modulus around the 2x-3 means that it will not allow negative values of y, so to the left of x=1.5, the straight line will \"break\" into a V shape and head back up to the top left\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now, mathematically, to see this \"rebounded\" portion of the line, we put a negative sign in front of the equation, like -(2x-3) = 7.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-2x+3 = 7
\n" ); document.write( "-2x = 4
\n" ); document.write( "x = -2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This can be seen if we ploy y = -(2x-3) against y=7, as shown: \"graph%28200%2C200%2C-10%2C10%2C-25%2C25%2C-2x%2B3%2C+7%29\"\r
\n" ); document.write( "
