Find all real numbers t$ such that 2/3 t - 1 < t + 7 \le -2t + 15$. Give your answer as an interval.
+9488 Find all real numbers t such that 23t−1 < t+7 ≤ −2t+15 . Give your answer as an interval.
_________
23t−1 < t+7 23t−t < 1+7 −13t < 8 t > −24
And
t+7 ≤ −2t+15 t+2t ≤ −7+15 3t ≤ 8 t≤83
t is bigger than -24 but less than or equal to 8/3
t must be in the interval (−24,83]_
