Hey,
\n" ); document.write( "So for this one we need to isolate one of the variables:
\n" ); document.write( "x+2y=8 => x=8-2y
\n" ); document.write( "Then substitute 8-2y for x in the second equation:
\n" ); document.write( "(8-2y) + 3y = 12
\n" ); document.write( "then subtract 8 from both sides and you get:
\n" ); document.write( "y = 4
\n" ); document.write( "I hope this helps!
\n" ); document.write( "
\n" );
