Here's the problem:
2[-7y-3(5-4y)+10]=10y-12 Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! 2[-7y-3(5-4y)+10]=10y-12
Divide both sides by 2 to get:
[-7y-3(5-4y)+10] = 5y - 6
[-7y -15 + 12y + 10] = 5y -6
5y -5 = 5y -6
If you subtract 5y from both sides you get this contradiction:
-5 = -6
================
The equation is "inconsistent" and has no solution.
The thing that was inconsistent was all those "y's".
You thought they all meant the same number; they don't.

Welcome back to the land of the learning.
