You can put this solution on YOUR website!
x + 4y = 41 ___ x = 41 - 4y\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting for x in the other equation ___ 4(41 - 4y) + 3y = 60 ___ 164 - 16y + 3y = 60\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "104 = 13y ___ 8 = y\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting ___ x + 4(8) = 41 ___ x = 9
\n" ); document.write( "
\n" );
