If a positive integer, list the values of x which satisfy the equation 3x - 4 < 6 and x - 1 > 0
- A. {1, 2, 3}
- B. {2, 3}
- C. {2, 3, 4}
- D. {2, 3, 4, 5}
Correct Answer: B. {2, 3}
Explanation
3x - 4< 6 = 3x< 6 = 4
3x< 10
x< \(\frac{10}{3}\)
x< 3.33 and x - 1 = 0
n > 1 = 1< x; since x is an integer, and 1< x3.33
x = {2, 3}
