Answer 1

To solve for x, we need to isolate x on one side of the equation.

Starting with the given equation:
-2x + 902 = 1518

We can first subtract 902 from both sides to get rid of that term on the left side:
-2x = 1518 - 902
-2x = 616

Next, we can divide both sides by -2 to solve for x:
x = 616 / -2
x = -308

Therefore, the best estimate for x is -300.
So the answer is: −300
