Question

Which of these compound inequalities
are equivalent to 4 < 6b – 2 < 28?​

Answer 1

The same way you would solve normal inequalities, only there are more sides to the inequality now. remember: what you do to one side you do it ALL sides

1.−3≤2x−1<5

2.−3+1≤2x−1+1<5+1

3.−22≤2x2<62

4.−1≤x<3
