Reann has stickers. She gives her friend half, and then her brother gives her 8 new ones. She ends up with 12 stickers. How many did she start with? Identify the operations to solve this problem.
To solve this problem, we can use the operations of division, addition, and subtraction.
1. First, Reann gives half of her stickers to her friend. This can be represented as dividing her original number of stickers by 2.
2. Then, her brother gives her 8 new stickers. This can be represented as adding 8 to the remaining number of stickers after giving half.
3. Finally, Reann ends up with 12 stickers. This can be represented as subtracting 12 from the total number of stickers she had after her brother gave her more.
Let's call the initial number of stickers Reann had "x".
Based on the given information, we can set up the following equation:
x/2 + 8 - 12 = x
Simplifying the equation, we can solve for x:
x/2 - 4 = x
To get rid of the fraction, we can multiply both sides of the equation by 2:
x - 8 = 2x
Subtracting x from both sides:
-8 = x
Therefore, Reann started with -8 stickers. However, this answer doesn't make sense in the context of the problem, as Reann cannot have a negative number of stickers. It appears that there may be an error in the formulation of the problem, as it is not possible to determine the initial number of stickers based on the information given.
