To find the value of x, we need to isolate it on one side of the equation. We can do this by subtracting 1,998 from both sides:
21x = 2,243 - 1,998
21x = 245
Now, divide both sides by 21:
x = 245/21
The best estimate for x would be the closest whole number to 245/21. Out of the given options, the best estimate would be 11.
Which of the following answers gives the best estimate for x given the following equation?
21x+1,998=2,243
