Final answer:
The equation that has only one solution is D. |–6x + 3| = 0.
Step-by-step explanation:
Among the given options, the equation that has only one solution is D. |–6x + 3| = 0.
To solve this equation, we need to remove the absolute value sign by setting the expression inside it equal to zero:
-6x + 3 = 0
Now, we can solve for x by isolating the variable:
-6x = -3
x = -3/-6
x = 1/2
Therefore, the equation |–6x + 3| = 0 has only one solution, which is x = 1/2.
