2y- = y-3

It looks like there might be a typo in your equation. If you meant to write the equation as \( 2y - y = -3 \) or something similar, please clarify.

Assuming you meant \( 2y - y = -3 \), we can simplify it:

1. Combine like terms on the left side: \[ 2y - y = y \] So the equation becomes: \[ y = -3 \]

If this is not what you intended, please provide clarification or correct the equation, and I'd be happy to help!
