How would you solve these absolute value equations?
1.3x1=x+4
2.3/k1=4

case1
3x1 = x+4
2x = 5
x = 5/2
case 2
3x1 = x  4
4x = 3
x = 3/4
There are also cases 3 and 4.
These would be (3x1) = (x+4)
and
(3x1) = x+4
but they yield the same answers as we already found
2. 3/k  1 = 4
3/k  1 = 4 OR 3/k  1 = 4
3  k = 4k or 3  k = 4k
3 = 5k or 3 = 3k
k = 3/5 or k = 1
