Question

Solve the inequality:

x - 7 > -3.1

a. x > 4.1
b. x > 3.9
c. x > -4.1
d. x > -10.1

Answer 1

To solve the inequality x - 7 > -3.1, add 7 to both sides, resulting in x > 3.9 as the solution.

Step-by-step explanation:

The inequality to solve is x - 7 > -3.1. To find the value of x, we need to isolate x on one side of the inequality.

1. Add 7 to both sides of the inequality to get x > 3.9.

Therefore, the correct answer is x > 3.9, which corresponds to option b.
