To solve the inequality, we need to isolate the variable x.
-7 ≤ 2x + 1 < 11
Subtract 1 from all parts of the inequality:
-7 - 1 ≤ 2x + 1 - 1 < 11 - 1
Simplify:
-8 ≤ 2x < 10
Divide all parts of the inequality by 2:
-8/2 ≤ 2x/2 < 10/2
Simplify:
-4 ≤ x < 5
Therefore, -4 is less than or equal to x, and x is less than 5.
-7 ≤ 2x +1 < 11
