These questions can have multiple answers
for instance,
a)
_+_=10.5
8.5 + 2 = 10.5
5.5 + 5 = 10.5
3.5 +7 = 10.5
5.25 + 5.25 = 10.5
b)
_-3.25 =_
7 - 3.25 = 3.75
7.25 - 3.25 = 4
10. 5 - 3.25 = 7.25
c)
if each _ have the same value
x + x = 10.5
2x= 10.5
x= 5.25
d)
if each _ have the same value
_-3.25 =_
x -3.25= x
x-x = 3.25
0= 3.25
In this case, each x cannot be the same, it would have to be a number that you subtract 3. 25 and it remains the same number. That is not possible.
but if i use x= 5.25
5.25- 3.25= 2
