If the table weighs 25 lb.,then 8 chairs weigh 72 lb.. That means that each chair weighs 9 lb.

.
This simple problem can be solved using one equation


    25 + 8x = 97,

    8x = 97 - 25

    8x = 72

     x = 72/8 = 9


giving the answer 9 pounds for the weight of a single chair.



It also can be solved in one line

    weight of a chair = %2897-25%29%2F8 = 72%2F8 = 9 pounds.



I prefer this short solution.


Which way do you prefer, is your choice.


It depends on the style of teaching in your school.


In my young age, we were taught to solve such simple problems in one line.
