Question

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 5 rows of the same length, he
has 9 chairs left over. If he arranges the chairs in 3 rows of that same length, he has 13 left over. How many
chairs does Liam have?
Liam has
chairs.

Answer 1

Answer:

19

Step-by-step explanation:

If the rows are the same length, the difference in the rows is 2 and the difference in the chairs is 4

4/2 is 2

each row is 2 chairs

5*2+9= 19

to check if you do it with the other example

3*2+13=19

Answer 2

Answer:

19 chairs

Step-by-step explanation:

c= chairs per row

5c +9  =  3c+13

2c= 4

c=2   (2 chairs per row)

(5x2)+3= 19

(3x2) +13= 19
