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