Which of the following answers gives the best estimate for x givin the following equation? - 2x +902=1518

Answer 1

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

First, we'll isolate the term with x by subtracting 902 from both sides:
-2x + 902 - 902 = 1518 - 902
-2x = 616

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

Therefore, the best estimate for x is -308.
