Question

Can anyone answer this Algebra problem? I can't solve it..

2|10b−10|−10=110

It's solving equations btw.

Answer 1

`2|10b-10|-10=110\\ 2|10b-10|=120\\ |10b-10|=60\\ 10|b-1|=60\\ |b-1|=6\\ b-1=-6 \vee b-1=6\\ b=-5 \vee b=7`

Answer 2

`2|10b-10|-10=110\ \ \ \ |add\ 10\ to\ both\ sides\\\\2|10b-10|=120\ \ \ \ |divide\ both\ sides\ by\ 2\\\\|10b-10|=60\\\Updownarrow\\10b-10=60\ or\ 10b-10=-60\ \ \ \ |add\ 10\ to\ both\ sides\\\\10b=70\ or\ 10b=-50\ \ \ \ |divide\ both\ sides\ by\ 10\\\\\huge\boxed{b=7\ or\ b=-5}`
