Step-by-step explanation:
Khan Academy and lemme explain.
The range has to be within 1-5, if its over, we know we won't have to get the wrong answer. For me, I honestly guessed the number 3, but then I had to put in each number in the equation. 2 was the solution, because they ended up the same.
2 + (1.25 * 2)
2 + 2.5 = 4.5
10 - (2.75 * 2)
10 - 5.5 = 4.5
4.5 = 4.5
Therefore the answer is 2.
