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? Identity the equations needed to solve this problem.
Let the total number of stickers Reann started with be "x".
Reann gives her friend half of the stickers, which is (1/2)x.
After giving her friend half, she has (1/2)x stickers left.
Then, her brother gives her 8 new stickers.
Therefore, the equation representing the number of stickers Reann has after her brother gives her 8 new ones is (1/2)x + 8.
She ends up with 12 stickers, so the equation representing this is (1/2)x + 8 = 12.
The equation needed to solve this problem is (1/2)x + 8 = 12.
