To solve for x in the equation 21x+1,998=2,243, we need to isolate the variable x.
By subtracting 1,998 from both sides of the equation, we get:
21x = 2,243 - 1,998
21x = 245
Then, divide both sides of the equation by 21 to solve for x:
x = 245 / 21
x ≈ 11.67
Therefore, the best estimate for x is 10.
