Best ResponseYou've already chosen the best response.0for me it was trial and error knowing that there needed to be an odd number of children I knew 3 doesn't work, 5 works for the boy having equal sisters and brothers but doesn't work for the girl, so try 7 works

Best ResponseYou've already chosen the best response.11 + 2x = x + y where x = girls, y = boys is one equation

Best ResponseYou've already chosen the best response.1that gives x + 1 = 1 + 2x giving x=0

Best ResponseYou've already chosen the best response.1i formulated an equation XD x  1 = y y  1 = x/2

Best ResponseYou've already chosen the best response.1x  1 = 0.5y is another so u have 1 + 2x = x + y x 1 = 0.5y is that right??

Best ResponseYou've already chosen the best response.1@cwrw238 i'll try to solve yours & you try mine :)

Best ResponseYou've already chosen the best response.1x  1 = y y  1 = 0.5x add x  2 = 0.5x x = 4 y = 41 = 3
