Which of the following answers gives the best estimate for x given the following equation?

Question

Create an image that displays a mathematical equation represented visually. Picture a whiteboard with written symbols equivalent to the question. Show the equation '21x + 1998 = 2243' detailed using chalk of different colors. Keep it as neat as possible to improve legibility. The equation's variables and numbers should be oversized and bold to capture attention. No other text or numbers should be on the board. The board stands against a subtly textured wall, and the chalk has left a slight dust trail.

Which of the following answers gives the best estimate for x given the following equation?

21x+1,998=2,243

Answer 1

To find the value of x, we can start by isolating x on one side of the equation. We can do this by subtracting 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 = 11.67

Among the given answer choices, the best estimate for x is 11.67.
