if a number is added to the numerator of 4/9 and the same number is subtracted from the denominator the result is -9. find the n
Sonja [21]
What a delightful little problem !

You said that       (4 + x) / (9 - x) = -9

Multiply each side by  (9 - x) :      (4 + x) = -9 (9 - x)

Eliminate parentheses:                4 + x = -81 + 9x

Add  81  to each side:                85 + x  =  9x

Subtract  'x'  from each side:         85  =  8x

Divide each side by  8  :              <em>85/8 = x </em>   (or 10.625)
