The answers are correct. There are two ways to solve it. To square both parts and solve a quadratic equation by checking each root, or to open up a modul by separating the initial equation in two cases.

Is there an easier way to solve these questions? I'm always scared that I'll miss out on some numbers. I can just place numbers and see but I know its not the right and best way !!!

vizz,

When we say lxl = 3 it implies that x = 3 or x = -3.

Check this out if you need more info.
http://www.purplemath.com/modules/absolute.htm

so |x-2| = (x-1)/2 implies
x-2 = (x-1)/2 or x-2 = -(x-1)/2

Solve these two eqns and you should arrive at
x = 3 or x = 5/3

There are two cases

1. x-2 = (x-1)/2 which yields x = 3

2. -(x-2) = (x-1)/2 which yields x = 5/3

For positive X => x-2=(x-1)/2=> x=3
For negative X=> -(x-2)=(x-1)/2=>x=5/3
