~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Let 'n' be the number of chairs in each row.


Write an equation as you read the problem

    set by   set by    total
    Alexis   Martin

    (4n+2)  +  5n     = 92.


Solve and find n

    9n = 92 - 2

    9n = 90

     n = 90/9 = 10.


<U>ANSWER</U>.  10 chairs in each of 9 rows plus 2 chairs left over.

Solved.
