Hello, Dianna,

CaptainBlack and topsquark have already explained how to solve those equations. Look here: http://www.mathhelpforum.com/math-he...-equation.html

If you are not certain what to do use the following method:

Code:`d - 4 = 7`

+ 4 | +4 add 4 on both sides

-------------- to get rid of the -4

d = 11

(For confirmation only: c = 54; a = -14)
