Well if you're solving for x this would be rather simple. 7x +1=68 , then you'd minus 1 from both sides. 7x = 67 then divide 67 by 7. The answer isn't a whole number so x would either be 67/7 or 9.57.. etc.

Total pounds of weight loss of bear in
months = 64.4 pounds
We have to determine the bear's weight change per month.
We will use unitary method to solve this problem.
So, total pounds of weight loss in 1 month = 
= 
= 
= 8.58
Since, we have to round to the nearest tenth.
Therefore, the bear's weight change per month is 8.6 pounds.
