Final answer:
The value of x in the equation 2x - 5 = 7 is 6.
Step-by-step explanation:
To find the value of x in the equation 2x - 5 = 7, we need to isolate x. First, add 5 to both sides of the equation: 2x - 5 + 5 = 7 + 5. This simplifies to 2x = 12. Then, divide both sides by 2: 2x/2 = 12/2. The equation becomes x = 6. Therefore, the value of x is not listed among the options (A) 2.7, (B) 16, (C) 7.3, or (D) 18.
