Question 1097747: what is the formula of this solving problems _+_=55 ?
what are the two missing numbers to makw it 55 ?
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! they could be any two numbers that add up to 55.
some examples:
0 _ 55
5 + 50
10 + 45
15 + 40
20 + 35
25 + 30
etc.
this assumes they're positive numbers.
if one of them could also be negative, then even more possible combinations.
some examples:
60 - 5
65 - 10
70 - 15
75 - 20
etc.
if one of them is given, say 33, then you have an equation such as:
33 + ? = 55
you need to find a number ? such that 33 + ? = 55
if you subtract 33 from both sides of this equation, you get ? = 55 - 33.
the difference between 55 and 33 is 22, therefore ? has to be 22.
your original equation of 33 + ? = 55 becomes 33 + 22 = 55 when ? = 22.
therefore, ? has to be equal to 22 and can be no other value once the other value in the addition has been set at 33.
