Which of the following answers gives the best estimate for x given the following equation? 21x+1,998=2,243 (1 point) Responses 10 10 1 1 100 100 1,000

1 answer

To solve the equation \( 21x + 1,998 = 2,243 \), we can follow these steps:

  1. Subtract 1,998 from both sides: \[ 21x = 2,243 - 1,998 \] \[ 21x = 245 \]

  2. Now, divide both sides by 21 to solve for \( x \): \[ x = \frac{245}{21} \] \[ x \approx 11.67 \]

Given the options provided (10, 1, 100, 1,000), the closest estimate for \( x \) is 10.
