You are planning for a simple party in your house. You have square tables which seat four people per table. When two tables are placed together, six people can be seated. If you have 22 guests in your party and you want them to sit together in a very long table, how many of these square tables should you prepare?​

Sagot :

Let x = no. of tables, y = no. of people:

y = 2x + 2

22 = 2x + 2

22 - 2 = 2x

20/2 = x

x = 10
