|y-8.0|<=1.5
y-8 ≤ 1.5 and -y+8 ≤ 1.5
y ≤ 9.5 and -y ≤ -6.5
y ≤ 9.5 and y ≥ 6.5
which can be written as
6.5 ≤ y ≤ 9.5
(or in words, y is between 6.5 and 9.5 inclusive
y-8 ≤ 1.5 and -y+8 ≤ 1.5
y ≤ 9.5 and -y ≤ -6.5
y ≤ 9.5 and y ≥ 6.5
which can be written as
6.5 ≤ y ≤ 9.5
(or in words, y is between 6.5 and 9.5 inclusive
