Question 92613: Please help me with this problem:
Solve the following absolute value inequalities:
The absolute value of (x+1)is less than or equal to the absolute value of (x-3).

I'm sorry I don't know how to key in a problem like that. I know how to solve a problem with absoulute value on one side, but does that same concept apply? Do you separate each side? I really have no idea where to go from here. Any help would be GREATLY appreciated.

|x+1| => |x-3|

Let us consider different cases with different sets of values of 'x':
1. x <= -1; then the inequality becomes: -(x+1) => -(x-3) i.e. -3 >= 1 which is absurd
2. -1<= x <= 3; then the inequality becomes: x+1 => -(x-3) i.e. x >= 1
3. 3<= x; then the inequality becomes: x+1 => x-3 i.e. 1 >= -3 which is true

So, the solution is: x >= 1.
