In a theater, there are 4 long rows of chairs, each with an equal number of chairs. There are 5 short rows of chairs, each with
an equal number of chairs. On a crowded day, the ushers added 2 chairs to each long row and 3 chairs to each short row. If x represents the number of chairs in each long row and y represents the number of chairs in each short row, the total number of chairs in the theater is given by the expression 4(x + 2) + 5(y + 3).
