kristen has 28 cousins. Subtract 10 from 58. just make sure that the total adds to 68
i sorry...i meant to say kristen has 58 cousins... subtract 10 from 68 then make sure the total adds to 68. Disregard first response
Let x = one number and x + 16 the other.

x + x + 16 = 50

2x = 34

x = 17

Can you take it from there?
Let x = Kristen's cousins and x +10 = Brad's cousins.

x + x + 10 = 58
