\n" ); document.write( "
\n" ); document.write( "2 x + 3 y = 25 .............1
\n" ); document.write( "3 x + 2 y = 30 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -2
\n" ); document.write( "Multiply (2) by 3
\n" ); document.write( "-4 x -6 y = -50
\n" ); document.write( "9 x 6 y = 90
\n" ); document.write( "Add the two equations
\n" ); document.write( "5 x = 40
\n" ); document.write( "/ 5
\n" ); document.write( "x = 8.00 OR 8
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "2 x + 3 y = 25
\n" ); document.write( "16 + 3 y = 25
\n" ); document.write( " 3 y = 25 -16
\n" ); document.write( " 3 y = 9
\n" ); document.write( " y = 3.00 OR 3
