Final answer:

To combine like terms in the expression 4y³ - 5x³ - 1 - 4y³ - 6 + 7 + 5y³ , group similar terms together and simplify to get 5y³ - 5x³ .

Step-by-step explanation:

To combine like terms in the expression 4y³ - 5x³ - 1 - 4y³ - 6 + 7 + 5y³, we need to group similar terms together and simplify.

Combining the y³ terms, we have 4y³- 4y³ + 5y³= 5y³.

Combining the x³ term, we have -5x³.

Combining the constant terms, we have -1 - 6 + 7 = 0.

Putting it all together, the simplified expression is 5y³ - 5x³.
