To find the value of x, we need to isolate x on one side of the equation.
Given: 21x + 1,998 = 2,243
First, we can subtract 1,998 from both sides of the equation to eliminate it from the left side:
21x + 1,998 - 1,998 = 2,243 - 1,998
21x = 245
Now, to solve for x, we can divide both sides of the equation by 21:
21x/21 = 245/21
x = 11.667
Therefore, the best estimate for x is 11.667.
