To find x in the equation -2x + 902 = 1,518, we first need to isolate x.
Starting with the given equation:
-2x + 902 = 1,518
We can begin by subtracting 902 from both sides to isolate -2x:
-2x = 616
Next, we divide both sides by -2 to solve for x:
x = 616 / -2
Simplifying further, we get:
x = -308
Therefore, the best estimate for x is -308.
Among the given options, the answer that matches the best estimate for x is:
−300 (or negative 300)
