Question

Which number sentence has exactly one solution? A. x + 5.4 > 8 B. 14(x – 5) = 13 C. 3x + 7.5 ≤ 9 D. 12x – 19 > 24

Answer 1

Answer: B: 14(x-5) is the answer

Answer 2

B. 14(x – 5) = 13

Explanation:

The equation that will have one solution must not be an inequality expression

Among the options, the only equation that fit this condition is 14(x-5) = 13

Expand

14(x-5) = 13

14x - 70 = 13

14x = 13+70

14x = 83

x = 83/14

x = 5.93

Since the equation has just one solution, hence the correct option is B
