combine like terms.
-6y + 7 - 7 + 4x² - 6x² - 3x² + 7y

Explanation:

Step1: Group like terms

Group the \(x^2\) terms, \(y\) terms, and constant terms:
\((4x^2 - 6x^2 - 3x^2) + (-6y + 7y) + (7 - 7)\)

Step2: Combine \(x^2\) terms

Calculate \(4x^2 - 6x^2 - 3x^2\):
\(4 - 6 - 3 = -5\), so \(-5x^2\)

Step3: Combine \(y\) terms

Calculate \(-6y + 7y\):
\(-6 + 7 = 1\), so \(y\)

Step4: Combine constant terms

Calculate \(7 - 7\):
\(7 - 7 = 0\)

Answer:

\(-5x^2 + y\)
