Respuesta :
(7z+11) because you add like terms so since 5 and 6 have no variable you would add them to get 11. You cant add 7z to anything because no other number has a variable
add 5 and 6
5+6=11
you can't add the 7z and the 11 because that is unknown+known
result is 7z+11
5+6=11
you can't add the 7z and the 11 because that is unknown+known
result is 7z+11
