This is easily solved by using two equations in 2 unknowns and solving the system. x + y = 111 x - y = 43 If have not yet had the pleasure of studying algebra and the answer is important to you, you could hope the numbers are positive integers and try all pair of numbers whose sum is 43: 1,42 2,41 3,40 and so on, until you find a pair whose difference is 43.
The numbers are 36, 37 and 38.
The best name for that is "a 111-sided shape". It really isn't worthwhile to find more specific names for hundreds of shapes whose only difference is the number of sides.
36 + 37 + 38 = 111
The numbers are 35, 37 and 39.
An easy way is to minus step by step eg: 111-28-9-56 111-28 then -9 then -56 OR 111-(28+9+56)
560
111 = 3*37

These are not real numbers.x + y = 24xy = 255By solving the system by the substitution method, we find that numbers are 12 + (√111)i and 12 - (√111)i.
1, 3, 37, 111
