Solving equations for x part 2
I dont understand 5 exercises besides those two,
I had done the second exercise yesterday with teh technique of the first one, it wasnt that I did it wrong but I wrote it wrong in my Homework, if you hadn't written it I wouldn't have noticed.(Cool)
Also there was a protest at the University so now I have 2 days to finish my homework.
5 other exercises that I don't know how to do:
a)solving for x:
b) I did an exercise and I got:
0 ≥ x ≤ -2
how do I write it in the <------------------------->
and in the interval notation
c)How do I find the two answers to:
3-|2x+4| ≤ 1
I have read and tried following what my book said and I can't get the answers that appear in the book.
