The solution to the compound inequality is -1 ≤ x < 5/2

How to solve the inequality

To solve the compound inequality 1 ≤ 2x + 3 < 8, you need to solve each part separately and then find the intersection of the solutions.

1 ≤ 2x + 3

1 - 3 ≤ 2x

-2 ≤ 2x

-1 ≤ x

2x + 3 < 8

2x < 8 - 3

2x < 5

x < 5/2

The solution to the compound inequality -1 ≤ x < 5/2

[-1, 5/2)

\(1 \leq 2x + 3 < 8\) is \(-1 \leq x < \frac{5}{2}\).

Solve 1 ≤ 2x + 3 < 8. Give solution as a graph and in interval notation.-example-1
