5y - 10 = -25

To solve the equation 5y - 10 = -25, we need to isolate the variable y by performing the necessary operations.

First, add 10 to both sides of the equation:

5y - 10 + 10 = -25 + 10

This simplifies to:

5y = -15

Next, divide both sides of the equation by 5 to solve for y:

5y/5 = -15/5

This simplifies to:

y = -3

Therefore, the solution to the equation 5y - 10 = -25 is y = -3.
