To find the best estimate for x, we need to solve the equation -2x + 902 = 1518.
First, let's subtract 902 from both sides of the equation:
-2x + 902 - 902 = 1518 - 902
Simplifying, we get:
-2x = 616
Now, let's divide both sides of the equation by -2:
-2x / -2 = 616 / -2
Simplifying, we get:
x = -308
So, the best estimate for x is -300 (negative 300).
Therefore, the correct answer is:
−300
