Question

Which of the following answers gives the best estimate for x given the following equation?
-2x + 902 = 1,518

-300
300
-600
600

Answer 1

To find the value of x, we need to isolate it on one side of the equation. We start by subtracting 902 from both sides:

-2x + 902 - 902 = 1,518 - 902
-2x = 616

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

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

Therefore, the best estimate for x is -300.
