    since there is an absolute value sign you have to set up 2 equations.

    one that says: |4x + 3| ≥ 19 and one that says: |4x + 3| (lessthan / equal to) - 19

    you have to set up 2 equations because there is an absolute value sign

    after that you solve for x. so start with the positive 19 equation when you solve for x what will you get.

    yes, now you got that one.. so just by looking at the answers you know its either a/d now do the second equation. what do you get?

    thats not all the way simplified but you're close , that simplifies down to ?

    yes which is also just -5.5 okay and so now you definitely know its either a/d okay the difference between a and d is that the middle word in a is "and" and the middle word in "d" is or.. do you know the difference between those?

    okay since you had the absolute value sign i told you before that you had to make two equations. and when you have to make two equations that means both of those answers need to be "included" so it would be "and". do you understand why?
