How do you solve y plus y equals 10?

Answer 1

You have to recognize that " y plus y " is the same as " 2y ".

This wouldn't be any problem if it was "house plus house" or "dog plus dog" ... you'd know

right away that it was "two houses" or "two dogs". But for some reason, a lot of people get

scared when they see " y plus y ", and totally freeze up.

y + y = 10

2y = 10

Divide each side by 2:

y = 5
