Answer 1

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
