2 x + 3 y = 200 .............1
\n" ); document.write( "
\n" ); document.write( "5 x + 4 y = 290 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -4
\n" ); document.write( "Multiply (2) by 3
\n" ); document.write( "-8 x -12 y = -800
\n" ); document.write( "15 x + 12 y = 870
\n" ); document.write( "Add the two equations
\n" ); document.write( "7 x = 70
\n" ); document.write( "/ 7
\n" ); document.write( "x = 10
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "2 x + 3 y = 200
\n" ); document.write( "20 + 3 y = 200
\n" ); document.write( " 3 y = 200 -20
\n" ); document.write( " 3 y = 180
\n" ); document.write( " y = 60
\n" ); document.write( "x= 10
\n" ); document.write( "y= 60
