the sum of the solutions to  is?
 is?
Sorry, but it is meaningless to speak of "the solution to an 
expression".  In order to have a solution, you must have either 
an equation or an inequality. In order to have an equation, 
there must be an equal sign " = " somewhere. In order to have 
an inequality, there must be a "greater than symbol", " > ", a
"less than" symbol " < ", a "greater than or equal symbol, " > ", 
or a "less than or equal to" symbol, " <, somewhere.
