Suppose there are x no of people in the stadium
So, we can write 2% of x is 50

Answer:
A.-
D.
E.
Step-by-step explanation:
Like terms must have the same variable, in this case x, and the same exponent, in this case 2. Since the original term is
, the like terms will be those that contain
, regardless of whether their coefficient or sign is different.
Analyzing the options:
A.-
We have the same variable and the same exponent
, so it is a like term.
B. 
You have the same variable x but not the same exponent. So it's not a like term of 
C.
Same variable
but as in the previous case, the exponent is different, it is a 3 and it should be a 2, so it is not a similar or like term.
D.
In this option we do have the
, so it is a like term of 
E.
It is also a like term because it contains the
.
In summary the like terms are:
A.-
D.
E.
Infinitely many solutions.

Cross multiplication, 3(9+x) = 63
27+3x = 63
3x = 63-27 = 36
x=36/3=12
