Answer 1

To find the value of x, we need to isolate it on one side of the equation.

Starting with −2x + 902 = 1,518, we can begin by subtracting 902 from both sides to move it to the other side of the equation:

−2x = 1,518 - 902

Simplifying, we get:

−2x = 616

To solve for x, we divide both sides of the equation by -2:

x = -616 ÷ -2

Simplifying further, we have:

x = 308

Therefore, the best estimate for x is 308.

Among the given answer choices, the closest estimate to 308 is 300. So, the best estimate for x is 300.
