I am having trouble with -4less than or equal to -3x-13 less than or equal to 26

-4 < -3x-13 < 26
Add 13 to all three parts of the inequality.
9 < 3x < 39
Divide all three parts by 3.
3 < x < 13

The < signs should all be "less than or equal, but I can't type that symbol with this computer

Take it apart into 2 statements
a) -4<=-3x-13

now combine it into -13<=x<=-3

or you could do it the way it sits

add 13
divide by -3, remember to reverse the inequality sign

which is the same result as in my first solution.

drwls, you missed the -sign in front of the 3x.
