There were 9 rows of chairs set up in the school gym. Each row had 20 chairs. After the students were seated, there were 12 empty chairs. How many chairs were filled. This problem is a two step equation.

180-12=168 seats were filled in

9x20-12 would be your equation

In order of operations multiplication in before subtraction

9x20=180 TOTAL seats

Now we do 180-12 to find the filled in seats since 12 were empty

180-12=168 seats were filled in
