It would be 4x +8
Step-by-step explanation: combine like terms 2x and 2x would be 4x and add 7 and one
Carlotta just needs to evaluate both expressions
Say y = 2
3y + 5y³ = 3(2) + 5(2)³ = 6 +40 = 46
8.y**4 <span> = 8*(2)**4 = 8*(16) = 128
This means that </span>3y + 5y³ ≠ 8.y**4
7=3x-5
12=3x
4=x
Hope this helps

3 + 8x - 2y - x + 1 + 4y
<u>Step 2: Simplify</u>
- Combine like terms (x): 7x + 3 - 2y + 1 + 4y
- Combine like terms (y): 7x + 2y + 3 + 1
- Combine like terms: 7x + 2y + 4
