Solve for x: The absolute value of x-1 is less than or equal to the absolute value of x-2
To do this you need to think about the meaning of absolute value.
That is if y < 0 then change its sign by multiplying by -1.
Hence you need to divide the line into three pieces, by cutting it at x = 1 and x = 2, and solve the equation in each piece.
Thus |x - 1| |x - 2| if and only if x 3/2.
