x-2y =10 .............1
\n" ); document.write( "y=10-x ---------2
\n" ); document.write( "Substitute y in (2)
\n" ); document.write( "2x-5y=25
\n" ); document.write( "2x-5(10 -x)= 25
\n" ); document.write( "2x-50+5x= 25
\n" ); document.write( "2x+5x =75
\n" ); document.write( "7x=75
\n" ); document.write( "/ 7
\n" ); document.write( "x= 75/ 7
\n" ); document.write( "Plug the value of x in (1)
\n" ); document.write( "2x-5y = 25
\n" ); document.write( "2*75/ 7-5y=25
\n" ); document.write( "150/ 7 + -5y = 25
\n" ); document.write( "-5 y = 25/ 7
\n" ); document.write( "/ -5
\n" ); document.write( "y= - 5/ 7
