Respuesta :
you mean, what is this number?
we can rephrase it like this: the sum of a number x and 8 is 15
which is:
x+8=15
we subtract 8 from both sides and we get
x=7
so the answer is 7.

Let the missing number be known as 's'
s + 8 = 15
Subtract 8 from both sides of the equation.
s + 8 = 15
-8 -8
---------------------
s = 7.
s + 8 = 15
Subtract 8 from both sides of the equation.
s + 8 = 15
-8 -8
---------------------
s = 7.
