..what i did not understand is this one: "ab solve for a", or are you trying to say solve for 'a' in the given equation? if it is:
to solve for 'a', transpose all terms to the other side such that 'a' will be left on one side of the equation,, in this case we transpose 'b' and 'c' on the left side but to do that you must reverse their signs (positive becomes negative):
x = a + b + c
x  b  c = a , or we can rewrite this as
a = x  b  c
so there,, i hope this helps :)
