can you help me to find an equivalant expression without parentheses

-(y-25)

-y + 25

A negative sign outside of parenthesis is telling you to multiply by -1 which makes positive numbers negative and negative numbers positive. So -y+25

To find an equivalent expression without parentheses for the expression -(y-25), you can apply the distributive property.

The distributive property states that for any numbers a, b, and c:

a * (b + c) = a * b + a * c

In this case, -(y-25) can be rewritten using the distributive property as:

-1 * (y - 25)

Applying the distributive property, we can distribute the -1 to both terms inside the parentheses:

-1 * y + (-1) * (-25)

Simplifying further, we have:

-y + 25

Therefore, an equivalent expression without parentheses for -(y-25) is -y + 25.
