Which of the following answer gives the best estimate for the x given the following equation. 21x+1,998=2,243
To find the value of x given the equation 21x + 1,998 = 2,243, we need to isolate the variable x.
First, subtract 1,998 from both sides of the equation to remove it from the left side:
21x + 1,998 - 1,998 = 2,243 - 1,998
This simplifies to:
21x = 245
Next, divide both sides of the equation by 21 to solve for x:
21x/21 = 245/21
This simplifies to:
x = 11.67
Therefore, the best estimate for x in the equation 21x + 1,998 = 2,243 is approximately 11.67.
