For this, the number we are looking for is x.
use this formula... 17 - 3 = 2x
therefore, 14 is your doubled number.
14 divided by two is 7.
your mystery number is 7
X + 4/5 = 11
x = 11 - 4/5
x = 55/5 - 4/5
x = 51/5 or 10 1/5
or u can do it this way..
x + 4/5 = 11.....multiply everything by common denominator of 5
5x + 4 = 55
5x = 55 - 4
5x = 51
x = 51/5 or 10 1/5
