    The answer to your question is 48 chairs

    Step-by-step explanation:

    Data

    5 rows - 3 chairs left over

    3 rows - 21 chairs left over

    Process

    1. - Write two equations each for each situation

    x = number of rows

    y = number of chairs

    Equation 1 y = 5x + 3

    Equation 2 y = 3x + 21

    2. - Solve the system by equality

    5x + 3 = 3x + 21

    5x - 3x = 21 - 3

    2x = 18

    x = 18/2

    x = 9

    3. - Find the total number of chairs

    y = 5 (9) + 3 y = 3 (9) + 21

    y = 45 + 3 y = 27 + 21

    y = 48 y = 48

    4. - Conclusion

    There are 48 chairs
