After 5 lessons of French, you have learned 20 vocab words. After 10 lessons, you know 40 vocab words. Write an equation
that gives the number of vocabulary words you know as a function of the number of the lessons you have had.
Label variables.
So, 5x+20
Isn't it?
Somebody prove me right/wrong.
Thank you.

u r right

number words=4*lessons

The complete equation is:
5x + 10x = 20 + 40
15x = 60
x = 60/15
x = ? 
4!!
