$11.\\2p+5r=q\ \ \ \ |subtract\ 5r\ from\ both\ sides\\\\2p=q-5r\ \ \ \ |divide\ both\ sides\ by\ 2\\\\\boxed{p=\dfrac{q-5r}{2}}$

$17.\\\dfrac{2}{5}(z+1)=y\ \ \ \ |multiply\ both\ sides\ by\ \dfrac{5}{2}\\\\z+1=\dfrac{5}{2}y\ \ \ \ |subtract\ 1\ from\ both\ sides\\\\\boxed{z=\frac{5}{2}y-1}$

Which polynomial correctly combines the like terms and puts the given polynomial in standard form?

Minchanka [31]

Answer: $-5x^3y^3+8x^4y^2-7xy^5+x^2y^4+8x^6$

Step-by-step explanation:

$-5x^3y^3+8x^4y^2-xy^5-2x^2y^4+8x^6+3x^2y^4-6xy^5$

$-5x^3y^3+8x^4y^2+(-xy^5-6xy^5)+(-2x^2y^4+3x^2y^4)+8x^6$

$-5x^3y^3+8x^4y^2+(-7xy^5)+(x^2y^4)+8x^6$

$-5x^3y^3+8x^4y^2-7xy^5+x^2y^4+8x^6$
