#### Question

Find the range of values of x which satisfy:

- 1/3 <= x/2 + 1 2/3 < 5 1/6

The graph in each of the following cases the values of x on the different real number lines:

1) x ∈ W

2) x ∈ Z

3) x ∈ R

#### Solution

-1/3 <= x/2 + 1 2/3 < 5 1/6

-1/3 - 5/3 <= x/2 < 31/6- 5/3

-6/3 <= x/2 < 21/6

-4 <= x < 7

1) if x  ∈ W, range of values of x is {0, 1, 2, 3, 4, 5, 6}

2) if x ∈ Z, the range of values of x is {-4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6}

3) if x ∈ R range of values of x is -4 <= x <7

Is there an error in this question or solution?
