Write an equation with a variable and state what the variable represents.

What do you think? I'll be glad to check your answer.
Well 18 / 3 = 6 would give the answer but that does not have a variable so I really don't know how to do this.
I'm glad you tried. Now I understand your thinking.

b = the variable representing the number of bulbs he bought.

3b = 18
Thank you!
You're welcome.
6b
