To find the best estimate for x in the given equation, we need to solve for x.
The equation is given as 21x + 1,988 = 2,243.
Subtracting 1,988 from both sides of the equation, we have:
21x = 2,243 - 1,988
21x = 255
Dividing both sides of the equation by 21, we get:
x = 255/21
x ≈ 12.14
Among the given answer choices, the best estimate for x is not included.
Which of the following answers gives the best estimate for x given the following equation.
21x + 1,988 = 2,243
A) 10
B) 100
C) 1
D) 1,000
