Let's mark a number with x.
\n" ); document.write( "Product of that number and -15 is P1.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"P1+=+-15x\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Product of that same number and 9 is P2.\r
\n" ); document.write( "\n" ); document.write( "\"P2+=+9x\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It says that P1 decreased by 25 is by 23 greater than P2.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"P1-25+=+P2%2B23\" , substitute P1 and P2 with above formulas
\n" ); document.write( "\"-15x-25+=+9x%2B23\" , move variables on the left and numbers on the right side
\n" ); document.write( "\"-15x-9x+=+23%2B25\" , combine
\n" ); document.write( "\"-24x++++=+48\" , divide both sides by -24
\n" ); document.write( "\"+++x++++=+-2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check:
\n" ); document.write( "P1 = -15*-2 = 30
\n" ); document.write( "P2 = 9*-2 = -18\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "P1-25 = 30-25 = 5
\n" ); document.write( "P2+23 = -18+23 = 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
