250X+40Y=1905
\n" ); document.write( "12X+5Y=19\r
\n" ); document.write( "\n" ); document.write( "250X+40Y=1905
\n" ); document.write( "-96X-40Y=-152 (MULTIPLIED BY -8)
\n" ); document.write( "---------------
\n" ); document.write( "154X =1753 OR X=1753/154 SUBSTITUTING X=1753/154 IN FORMULA #2 WE GET\r
\n" ); document.write( "\n" ); document.write( "12(1753/154)+5Y=19 OR 21036/154+5Y=19 OR 5Y=19-21036/154 OR \r
