3 x -2 y = -12 .............1
\n" ); document.write( "4 x + 3 y = 1 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 3
\n" ); document.write( "Multiply (2) by 2
\n" ); document.write( "9 x -6 y = -36
\n" ); document.write( "8 x + 6 y = 2
\n" ); document.write( "Add the two equations
\n" ); document.write( "17 x = -34
\n" ); document.write( "/ 17
\n" ); document.write( "x = -2
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "3 x -2 y = -12
\n" ); document.write( "-6 -2 y = -12
\n" ); document.write( " -2 y = -12 + 6
\n" ); document.write( " -2 y = -6
\n" ); document.write( " y = 3
\n" ); document.write( "(-2,3) \n" ); document.write( "

\n" );
