a) ok first take the 5 to the other side

2|x-3| = 14
|x-3| = 7

so x-3 = 7 or x-3 = -7
x = 10 or x = -4

b) That's pretty much straightforward from there.

1. first i would take add the 5 to the other side to get 2lx-3l=14, then i would devide both sides by 2 to get lx-3l=7. then this rly turns into 2 problems being x-3=-7 and x-3=7, add 3 over on both equations to solve, getting x=-4 and 10

2, as far as graphing goes im not sure how to show u on a computer, use a scientific calculator if u have 1 with the steps i showed u above
