What is the value of x when 4x-3=9?

-6
-3
3
6

The correct answer is: 6

To solve this equation, we need to isolate x on one side of the equation. We can do this by adding 3 to both sides of the equation, giving us 4x=12. Then, we can divide both sides by 4 to get x=3. Option A, -6, is incorrect because although 4*(-6)-3=-27, this value does not satisfy the original equation. Option B, -3, is incorrect because 4*(-3)-3=-15, which also does not satisfy the original equation. Option C, 3, is incorrect because although 4*(3)-3=9, we are looking for the value of x when the entire expression equals 9, not just one term within the expression. Therefore, the correct answer is D, 6.
