    I think you want to know about the value of x and y. Based on this assumption, i am answering the question.

    y = x + 5

    20x + 25y = 1115

    Putting the value of y from the first equation in the second equation, we get

    20x + 25 (x + 5) = 1115

    20x + 25x + 125 = 1115

    45x = 1115 - 125

    45x = 990

    x = 22

    Then

    y = x + 5

    = 22 + 5

    = 27

    From the above deduction, it can be concluded that the elementary classroom will have 22 new desks and the secondary classroom would have 27 desks.
