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.

1 answer

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.
