3.00 x -5.00 y = 1.00 .............1
\n" ); document.write( "Total value
\n" ); document.write( "6.00 x -10.00 y = 4.00 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 2.00
\n" ); document.write( "Multiply (2) by 1.00
\n" ); document.write( "6.00 x -10.00 y = 2.00
\n" ); document.write( "6.00 x -10.00 y = 100.00
\n" ); document.write( "Add the two equations
\n" ); document.write( "12.00 x = 102.00
\n" ); document.write( "/ 12.00
\n" ); document.write( "x = 8.50
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "3.00 x -5.00 y = 1.00
\n" ); document.write( "25.50 -5.00 y = 1.00
\n" ); document.write( " -5.00 y = 1.00 -25.50
\n" ); document.write( " -5.00 y = -24.50
\n" ); document.write( " y = 4.90
