Which of the following answers gives the best estimate for x given the following equation?−2x+902=1,518
300
-300
600
-600
To find the value of x, we can start by isolating the variable. We can do this by subtracting 902 from both sides of the equation:
−2x + 902 - 902 = 1,518 - 902
Simplifying the equation:
−2x = 616
Now, we divide both sides by -2:
−2x / -2 = 616 / -2
Simplifying further:
x = -308
Therefore, the best estimate for x is -300.
