negative four is at least six less than a number & the sum of a negative two & nine times a number is less than seventy nine

Answer 1

• 2 ≤ x < 9 or x = [2, 9)

Explanation:

Negative four is at least six less than a number

• -4 ≤ x - 6 ⇒ x ≥ 2

Sum of a negative two & nine times a number is less than seventy nine

• -2 + 9x < 79 ⇒ 9x < 81 ⇒ x < 9

Combined inequality:

• 2 ≤ x < 9 or x = [2, 9)
