-6 - 2y^2 + 6x - 4x + 1 + 7y^2 - y^2

Explanation:

Step1: Combine x - terms

$(6x - 4x)=2x$

Step2: Combine y - squared terms

$(-2y^{2}+7y^{2}-y^{2})=(-2 + 7-1)y^{2}=4y^{2}$

Step3: Combine constant terms

$(-6 + 1)=-5$

Step4: Write the combined - terms expression

$4y^{2}+2x - 5$

Answer:

$4y^{2}+2x - 5$
