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

Answer 1

To estimate the value of x, we need to isolate the variable x in the equation. Let's start by subtracting 902 from both sides of the equation:

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

This simplifies to:

-2x = 616

Now, divide both sides of the equation by -2 to solve for x:

-2x / -2 = 616 / -2

x = -308

Therefore, the best estimate for x in the equation -2x + 902 = 1,518 is -308.
