3 x + 2 y = 5 .............1
\n" ); document.write( "
\n" ); document.write( "5 x -9 y = -4 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 9
\n" ); document.write( "Multiply (2) by 2
\n" ); document.write( "27 x 18 y = 45
\n" ); document.write( "10 x -18 y = -8
\n" ); document.write( "Add the two equations
\n" ); document.write( "37 x = 37
\n" ); document.write( "/ 37
\n" ); document.write( "x = 1
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "3 x + 2 y = 5
\n" ); document.write( "3 + 2 y = 5
\n" ); document.write( " 2 y = 5 -3
\n" ); document.write( " 2 y = 2
\n" ); document.write( " y = 1 \r
\n" ); document.write( "\n" ); document.write( "x=1, y=1
\n" ); document.write( " \n" ); document.write( "
