Answer:
There are infinitely many answers to this question.
Step-by-step explanation:
This question can be written as 4 ( __ + __) = 48
Simplifying gives us
( __ + __) = 12, so any summation of 2 numbers that equals 12 will solve this.
There are infinitely many since you will use PEMDAS to simplify what is in the parethesis before multiplying by 4.
Some examples are
1 and 11
0 and 12
-48 and 60
0.5 and 11.5
192 and -180
...as you can see, there can be infinitely many numbers combinations written to satisfy this equation.
