multiply first equation by 10
\n" ); document.write( "second equation by 100\r
\n" ); document.write( "\n" ); document.write( "3 x + 2 y = 40 .............1
\n" ); document.write( "104 x + 50 y = 100 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -25
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "-75 x -50 y = -1000
\n" ); document.write( "104 x + 50 y = 100
\n" ); document.write( "Add the two equations
\n" ); document.write( "29 x = -900
\n" ); document.write( "/ 29
\n" ); document.write( "x = -31.03
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "3 x + 2 y = 40
\n" ); document.write( "-93.1 + 2 y = 40
\n" ); document.write( " 2 y = 40 + 93.1
\n" ); document.write( " 2 y = 133.1
\n" ); document.write( " y = 66.55
