5 x -2 y = 30 .............1
\n" ); document.write( "
\n" ); document.write( "-2 x + 2 y = 0 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 1
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "5 x -2 y = 30
\n" ); document.write( "-2 x + 2 y = 0
\n" ); document.write( "Add the two equations
\n" ); document.write( "3 x = 30
\n" ); document.write( "/ 3
\n" ); document.write( "x = 10
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "5 x -2 y = 30
\n" ); document.write( "50 -2 y = 30
\n" ); document.write( " -2 y = 30 -50
\n" ); document.write( " -2 y = -20
\n" ); document.write( " y = 10
\n" ); document.write( "x=10, y=10 \n" ); document.write( "

\n" );
