Answer:
7x-5 = 9
x = 2
Step-by-step explanation:
Let x be the number
7x-5 = 9
Add 5 to each side
7x-5+5 = 9+5
Divide each side by 7
7x = 14
7x/7 = 14/7
x=2
If you had one row, you would have 22 chairs.
If you had two rows, you would have 22+22=44 chairs.
If you had three rows, you would have 22+22+22 chairs, or 66 chairs.
See the pattern?
If you had 40 rows, you would add 22 40 times, or 22*40=880 chairs.
Hope this helps!
