It would be 8. To solve, look at it like this: 8-b=(-2). I would then look at a number line or create one if your not to sure of yourself. 8-8=0, and then 0-2=-2. 2+8=10 (the numbers you subtracted). So the answer is 10.

Answer:
10 tickets
Step-by-step explanation:
25 + 5x = 35 + 4x

5x = 35 - 25 + 4x
subtract 4x from both sides...
5x - 4x = 10
x = 10, 10 tickets.
