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

Answer 1

To find the value of x, we need to isolate it on one side of the equation.

First, we can subtract 902 from both sides of the equation:

−2x = 1,518 - 902

Simplifying this equation, we get:

−2x = 616

To solve for x, we can divide both sides of the equation by -2:

x = 616 / -2

x = -308

Therefore, the best estimate for x is -308.
