Suppose the farmer's initial plan is to plant the first tree and then plant the second tree $x$ feet away, and the third tree $x$ feet further on so there are $x$ feet between the trees. Thus, after the first tree the farmer needs $\frac{1320}{x}$ trees. Suppose he increases the distance between the trees to $x + 5$ feet. How many trees will he need after the first tree? This is 44 less than the number in his initial plan. Solve for x. Make sure you check your answer,
