Which of the following answers gives us the best estimate for x given the following equation 21x + 1,998 = 2,243

1 answer

To solve the equation 21x + 1,998 = 2,243, we need to isolate x on one side of the equation.

First, we subtract 1,998 from both sides of the equation:
21x + 1,998 - 1,998 = 2,243 - 1,998
21x = 245

Next, we divide both sides of the equation by 21 to solve for x:
21x/21 = 245/21
x = 245/21

Out of the provided answers, the best estimate for x would be x = 245/21.
