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

Answer 1

To solve the equation \(-2x + 902 = 1518\), follow these steps:

1. Subtract 902 from both sides of the equation:

   \[-2x + 902 - 902 = 1518 - 902\]

   This simplifies to:

   \[-2x = 616\]

2. Next, divide both sides by -2:

   \[x = \frac{616}{-2}\]

   This gives:

   \[x = -308\]

Therefore, the best estimate for \(x\) is \(-308\).
