how to find sum of variable
c1 + c2 + c3 for expression combinations:
a1 + a2 + a3 + b1 + b2 + b3 + c1 + c2 + c3 == 45 a1 + a2 == 10 b1 + b2 == 3 a3 + b3 == 14
c1+c2+c3 by looking it this should give ans like
c1 + c2 + c3 = 18 all variable and >0 integer only I also want to do more combination if possible.
