Question 840838
A linear expression, using unknown variable x, and constants are a , b and c :


{{{ax+bx+c}}}----------this is simplifyable.


Combine like terms, to obtain {{{(a+b)x+c}}}.
Now you can ask, what is the coefficient of the leading term and what is the constant term.
(*)  The coefficient on the leading term is (a+b).
(*)  the constant term is c.


Now you should be able to answer YOUR question.
