You can put this solution on YOUR website!
y=2x
\n" ); document.write( "x+y=12
\n" ); document.write( "We are already given what y =, so use that in the other equation to find the answer for x;
\n" ); document.write( "x+ 2x=12
\n" ); document.write( "3x=12
\n" ); document.write( "x=4
\n" ); document.write( "Now plug that into the first equation to find y;
\n" ); document.write( "y=2(4)
\n" ); document.write( "y=8
\n" ); document.write( "Hope you understand!
