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

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

Let's simplify the equation:

-2x + 902 = 1518

First, we subtract 902 from both sides to isolate the term with 'x':

-2x + 902 - 902 = 1518 - 902

This simplifies to:

-2x = 616

Next, we divide both sides of the equation by -2 to solve for 'x':

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

The -2's cancel out, and we're left with:

x = -308

Therefore, the best estimate for x is -308.
