To find the value of x, we need to isolate it on one side of the equation.
Starting with -2x + 902 = 1,518, we can subtract 902 from both sides:
-2x = 1,518 - 902
-2x = 616
Dividing both sides by -2, we get:
x = -616 / -2
x = 308
Therefore, the best estimate for x is 300, which is the closest whole number.
Which of the following answers gives the best estimate for x given the following equation?
-2x + 902 = 1,518
