Question

решите двойные неравенства 2<4x+3днлёное на три≤3

Answer 1

[tex]2< frac{4x+3}{3} leq 3 \ 6<4x+3 leq 9 \ 3<4x leq 6 \ frac{3}{4}<x leq frac{6}{4} \ 0.75<x leq 1.5  [tex]

Answer 2

2< (4x+3)/3 ≤3
2*3 < 4x+3 ≤3*3
6 < 4x+3 ≤ 9
6-3 < 4x ≤ 9-3
   3 < 4x ≤ 6
3/4 < x ≤ 6/4
0,75 < x ≤1,5
x∈(0,75;1,5]
