We can solve this

0  ≤ [ -2x + 5] / 7  <  1       multiply both sides by 7

0 ≤  -2x + 5  <   7

We have two inequalities

0 ≤ -2x + 5                            -2x + 5 < 7

Subtract  5 from both sides

-5 ≤ -2x                                                              -2x < 2

Divide both sides by -2

Reverse the inequality sign

5/2 ≥ x                                                                  x > - 1

So....the  solution interval for   this is    -1 < x  ≤ 5/2
