You can put this solution on YOUR website!
x + 2y = 7
\n" ); document.write( "x + 6y = 1
\n" ); document.write( "------------ subtraction eliminates x
\n" ); document.write( "0 - 4y = 6
\n" ); document.write( "-4y = 6
\n" ); document.write( "y = $\"6%2F%28-4%29\"$
\n" ); document.write( "y = -1.5
\n" ); document.write( ":
\n" ); document.write( "Find x using x + 6y = 1
\n" ); document.write( "x + 6(-1.5) = 1
\n" ); document.write( "x - 9 = 1
\n" ); document.write( "x = 1 + 9
\n" ); document.write( "x = 10
\n" ); document.write( ":
\n" ); document.write( "The ordered pair 10, -1.5
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in the 1st equation
\n" ); document.write( "x + 2y = 7
\n" ); document.write( "10 + 2(-1.5) = 7
\n" ); document.write( "10 - 3 = 7, confirms our solution
\n" ); document.write( " \n" ); document.write( "

\n" );
