To determine the right equation for the problem, let's break down Emma's movements.
- On her first turn, Emma rolled a number
and moved spaces (since a card increased her movement by 8). - On her second turn, she rolled 3 times her previous roll, so she moved
, but her friend played a card that decreased her movement by 4 spaces, resulting in her moving spaces.
Since it's given that she moved the same number of spaces on both turns, we can set up the equation:
This means the correct equation to find
