You can put this solution on YOUR website!
6 x -7 y = -56 .............1
\n" ); document.write( "4 x -1 y = -52 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -1
\n" ); document.write( "Multiply (2) by 7
\n" ); document.write( "-6 x 7 y = 56
\n" ); document.write( "28 x + -7 y = -364
\n" ); document.write( "Add the two equations
\n" ); document.write( "22 x = -308.00
\n" ); document.write( "/ 22
\n" ); document.write( "x = -14
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "6 x + -7 y = -56
\n" ); document.write( "-84 + -7 y = -56
\n" ); document.write( " -7 y = -56 + 84
\n" ); document.write( " -7 y = 28
\n" ); document.write( " y = -4
\n" ); document.write( " \n" ); document.write( "

\n" );
