Omar is on a diet to lose some weight. he is losing weight at a rate of 2 pounds per week. after 6 weeks, his weight is 204 pounds. linear equation and how many weeks it will take omar to reach his target weight of 189 pounds.

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.
