Simplify. -2y-5(-5z+5y)+2z

Sure, let's simplify the expression step by step:

-2y - 5(-5z + 5y) + 2z

First, distribute the -5 inside the parentheses:

-2y - (-25z + 25y) + 2z

This simplifies to:

-2y + 25z - 25y + 2z

Next, combine like terms:

(25z + 2z) + (-2y - 25y)

This simplifies to:

27z - 27y

So, -2y - 5(-5z + 5y) + 2z simplifies to 27z - 27y.
