Which of the following give's the best estimate for x in the equation below.

-2x+902=1518
300
-300
600
-600

1 answer

To find the best estimate for x in the equation -2x + 902 = 1518, we need to isolate x.

Starting with the equation, we can begin by subtracting 902 from both sides:

-2x + 902 - 902 = 1518 - 902
-2x = 616

Next, we divide both sides by -2 to solve for x:

(-2x)/-2 = 616/-2
x = -308

Therefore, the best estimate for x is -300.

The correct answer choice is -300.
