When I use Solve-function,You may get answers you don’t want to know.
For example,
In:=Solve[a+b+c+d.....&&..........,{a,b,c,d},Integers]
Out= {a -> 1, b -> 3, c -> 1, d -> 2}, {a -> 1, b -> 4, c -> 1, d -> 2}, {a -> 1, b -> 5, c -> 1, d -> 2}, {a -> 1, b -> 6, c -> 1, d -> 2}......
When you do not want to know the answers of a and b.
I just want to know what happens to the values ?? of c and d.
As the number of results increases, it becomes more difficult to find the combination of numbers c and d. What should I do in this case?
So,I do this.
In:=Solve[a+b+c+d.....&&..........,{c,d},Integers]
Out=c -> ConditionalExpression[2,.....
However, it did not work. What should I do?
