Solve the following inequality:

|10 + 4x| < 14

• x < 1 and x > −6

• x < 1 or x > −6

• x < 6 and x > −6

• x < 1 or x > −1

Review the work shown solving the inequality. Should the inequality symbol been reversed?

• Yes, because 2 is positive.

• ​No, because 2 is positive.

• ​Yes, because −4 is negative.

• No, because −4 is negative.
