Final answer:

To find the value of x that makes the equation true, simplify the equation, isolate the term with x, convert the percentage to a decimal, combine like terms, and solve for x.

Step-by-step explanation:

To find the value of x that makes the equation true, we need to solve the equation for x. First, let's simplify the equation:

12% - 15 = 6 - 3x

To isolate the term with x, we can move it to one side of the equation:

3x = 6 - 12% + 15

Next, let's convert the percentage to a decimal:

3x = 6 - 0.12 + 15

Combine like terms:

3x = 21.88

Finally, divide both sides of the equation by 3 to solve for x:

x = 21.88 ÷ 3 = 7.29

The value of x that makes the equation true is approximately 7.29. None of the given options is correct.
