Our basis would be 204 pounds. His original weight, 6 week ago, must be
204 + 2(6) = 216 pounds
But, we have to find the number of weeks having known the present weight (204 pounds) and the target weight (189). The linear equation would be
189 = 204 - 2(number of weeks)
Number of weeks = (204-189)/2
Number of weeks = 7.5
The total number of weeks would then be 6 weeks + 7.5 weeks. It would take Omar 13 and a half weeks since he started his diet to reach his target weight.
