Question

Which is the best estimate of x based on rounding the constants and coefficients in the equation to the nearest integer 6.15 (x - 8,86) = 21.83

Answer 1

Your answer would be x = 12.41 

6.15 (x - 8.86) = 21.83
      *6.15 * 6.15

6.15x - 54.49 = 21.83
         + 54.49  + 54.49

6.15x = 76.32
/6.15    /6.15

x = 12.41
