Which of the following answers gives the best estimate for x given the following equation?

−2x+902=1,518'

600

−300

−600

300

1 answer

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

Starting with the equation -2x + 902 = 1,518, we can subtract 902 from both sides first:
-2x = 1,518 - 902
-2x = 616

Next, we divide both sides of the equation by -2 to solve for x:
x = 616 / -2
x = -308

None of the provided answer choices are an exact match to the calculated value of x. However, the closest estimate from the given choices is -300.
