10(-2x+1) = -19(x+1)

I get the answer:

x = -29

However, the book says that the answer is:

x = 29

Did I make a mistake, or is it just a typo in the book? Any help would be greatly appreciated.

Thanks, - Xel

You made a mistake. Show what you did, and I'll tell you specifically where you went wrong.

You did not show any steps. It is much simpler to be helpful if you show what you did.

10(-2x+1) = -19(x+1)

-20*x + 10 = -19*x - 19

Add 19*x

-20*x + 19*x + 10 = -19*x + 19*x - 19

(-20*x + 19*x) + 10 = (-19*x + 19*x) - 19

-x + 10 = 0 - 19

-x + 10 = - 19

My guess is something went wrong right around there.
