Question

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 x on one side of the equation. We can do this by first subtracting 902 from both sides of the equation.

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

This simplifies to:

-2x = 616

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

-2x / -2 = 616 / -2

This simplifies to:

x = -308

Therefore, the best estimate for x is -308.
