To find the best estimate for x, we can solve the equation. Adding 2x to both sides of the equation gives us 902 = 1518 + 2x. Subtracting 1518 from both sides gives us 902 - 1518 = 2x, which simplifies to -616 = 2x. Dividing both sides by 2 gives us -308 = x. Therefore, the best estimate for x is -300, which is the closest whole number to -308.
So the correct answer is:
−300
