You can put this solution on YOUR website!
-12 x + 27 y = 60 .............1
\n" ); document.write( "
\n" ); document.write( "-6 x -6 y = 30 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 2
\n" ); document.write( "Multiply (2) by 9
\n" ); document.write( "-24 x 54 y = 120
\n" ); document.write( "-54 x -54 y = 270
\n" ); document.write( "Add the two equations
\n" ); document.write( "-78 x = 390
\n" ); document.write( "/ -78
\n" ); document.write( "x = -5
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "-12 x + 27 y = 60
\n" ); document.write( "60 + 27 y = 60
\n" ); document.write( " 27 y = 60 -60
\n" ); document.write( " 27 y = 0
\n" ); document.write( " y = 0
\n" ); document.write( "(-5,0) is the solution \n" ); document.write( "

\n" );
