I chose problem #5
-4<3x-22<2
21<-3x<24
-7>x>-8
-8<x<-7
This is how I solved the problem:
4<3x22<2
Add 22 to all parts
4+22<3x22+22<2+22 =
18<3x<24
Divide all parts by -3
18/-3<-3x/-3<24/-3=
6>x>8
So what I think happened in the original problem was that

I chose problem #4. 3x(x+2)-(5x-3) I believe that this problem has two errors. The first would be the
double negative rule and the second would be combining like terms.
3x(x+2)-(5x-3)
3x^2+6x-5x+3
3x^2+x+3
I believe this error can be avoided by following
