You can put this solution on YOUR website!
3x + y = 6
\n" ); document.write( "4x +2y = 8
\n" ); document.write( "multiply the 1st equation by 2, subtract the 2nd equation
\n" ); document.write( "6x + 2y = 12
\n" ); document.write( "4x + 2y = 8
\n" ); document.write( "--------------subtraction eliminates y, find x
\n" ); document.write( "2x = 4
\n" ); document.write( "x = 4/2
\n" ); document.write( "x = 2
\n" ); document.write( ":
\n" ); document.write( "Find y using the 1st equation
\n" ); document.write( "3(2) + y = 6
\n" ); document.write( "6 + y = 6
\n" ); document.write( "y = 6 - 6
\n" ); document.write( "y = 0
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check the solutions in the 2nd equation
\n" ); document.write( "4x + 2y = 0
\n" ); document.write( "4(2) + 2(0) = 8 \n" ); document.write( "

\n" );
