There are 3x-2 trees planted in each row of a rectangular Parcel of land. If there are a total of 24x-16 trees planted and the parcel, how many rows of trees are there in the parcel?

Let's call the number of rows 'R' . (Clever ?)There are (3x -2) trees in each row, and there are 'R' rows,so the total number of trees is [ R times (3x-2) ].But the problem told you that the total number of trees is (24x-16).So       R(3x - 2) = (24x - 16)For a quick, happy ending, how about factoring '8' out of the right side:       R(3x - 2) = 8(3x - 2)Is it jumping out at you yet ?If not, then divide each side by (3x - 2) :       R      =      8There are eight (8) rows of trees.
