The aim is to separate the letters and numbers so they are on different sides of the equals. Move the +11 over to the other side by making it -11 (do the opposite of what it was originally) so you get 8d = 35 -11, tidy that up to 8d = 24. Now you need to move the 8 which is joined to the by times. When it goes over to the other side, do the opposite which is divide so you get d = 24/8. Tidy that up so your final answer is d = 3. To double check you are correct you take your value of 3, put it back in the original question and see if it works: 8 x 3 + 11 = 35 which is true so you are correct.
