2x+12y=-70.
\n" ); document.write( "/2
\n" ); document.write( "x+6y=-35\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "12x+3y=63
\n" ); document.write( "/3
\n" ); document.write( "4x+y=21\r
\n" ); document.write( "\n" ); document.write( "1 x + 6 y = 35 .............1
\n" ); document.write( "Total value
\n" ); document.write( "4 x + 1 y = 21 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 1
\n" ); document.write( "Multiply (2) by -6
\n" ); document.write( "1 x 6 y = 35
\n" ); document.write( "-24 x -6 y = -126
\n" ); document.write( "Add the two equations
\n" ); document.write( "-23 x = -91
\n" ); document.write( "/ -23
\n" ); document.write( "x = 3.96
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x + 6 y = 35
\n" ); document.write( "4 + 6 y = 35
\n" ); document.write( " 6 y = 35 -4
\n" ); document.write( " 6 y = 31
\n" ); document.write( " y = 5.17
\n" ); document.write( " \n" ); document.write( "
\n" );
