3 x + 1 y = 10 .............1
\n" ); document.write( "0.67 x + 1 y = 3 .............2
\n" ); document.write( "
\n" ); document.write( "multiply (1)by -1
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "-3 x -1 y = -10
\n" ); document.write( "0.67 x + 1 y = 3
\n" ); document.write( "Add the two equations
\n" ); document.write( "-2.33 x = -7
\n" ); document.write( "/ -2.33
\n" ); document.write( "x = 3
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "3 x + 1 y = 10
\n" ); document.write( "9 + 1 y = 10
\n" ); document.write( " 1 y = 10 -9
\n" ); document.write( " 1 y = 1
