To find the best estimate for x, we need to solve the equation -2x + 902 = 1,518.
Let's solve it step by step:
First, subtract 902 from both sides of the equation:
-2x + 902 - 902 = 1,518 - 902
-2x = 616
Next, divide both sides of the equation by -2:
-2x / -2 = 616 / -2
x = -308
Therefore, the best estimate for x in this equation is -300.
So, the correct answer is C) -300
which of the following answers gives the best estimate for x given the following equation?
