To find the best estimate for x, we need to isolate x on one side of the equation.

Starting with -2x + 902 = 1,518, let's subtract 902 from both sides:
-2x + 902 - 902 = 1,518 - 902
-2x = 616

Now we'll divide both sides by -2 to solve for x:
(-2x)/-2 = 616/-2
x = -308

Since the options are given in whole numbers, the best estimate for x is -300. Therefore, the answer is A. 300.
