x + 50 = 120
50x = 120
50 + 120 = x
x - 120 = 50

Let's analyze each question one by one:

1. **Jalen is saving for a new tablet:**
Jalen needs to save a total of $120 and has already saved $50. The equation to represent how much more he needs to save (x) is:
\[
x + 50 = 120
\]
Correct answer: **x + 50 = 120**

2. **Isabella bought packs of stickers:**
Each pack costs $3, and she spent a total of $18 on stickers. The equation that represents the number of packs (x) she bought is:
\[
3x = 18
\]
Correct answer: **3x = 18**

3. **Byron's savings account:**
Byron spent $40 and has $80 left. Let x be the amount of money he had before spending. The equation to find how much he had is:
\[
x - 40 = 80
\]
Rearranging gives:
\[
x = 80 + 40 = 120
\]
Correct answer: **x = $120**

4. **Zayan brought Oreos:**
Zayan shares Oreos with 8 friends, giving each friend 3 Oreos. The equation representing the total number of Oreos (x) Zayan brings is:
\[
3x = 8
\]
This seems to be a bit off since he should have given away a total of \(3 \times 8 = 24\) Oreos. The equation based on number of Oreos is:
\[
x = 3 \times 8 = 24.
\]
But the closest answer available that matches \(3 \times x = 24\) is:
\[
x/3 = 8; x = 24
\]
Correct answer: **x/3 = 8; x = 24**

So, the correct answers are:
1. \(x + 50 = 120\)
2. \(3x = 18\)
3. \(x = 120\)
4. \(x/3 = 8; x = 24\)
