Two students in the same Spanish class, Sasha and Irwin, plan to get together after school to make vocabulary flashcards. Sasha started and has already made 6 flashcards. Irwin hasn't started yet. Since Sasha makes 3 flashcards per minute and Irwin makes 6 flashcards per minute, Irwin will soon have the same number of flashcards.
Write a linear equation for each student. How long will it take Sasha and Irwin to have the same number of flashcards and how many flashcards will each have?
What is
Sasha: y = 3x + 6
Irwin: y = 6x
Sasha and Irwin will each have 12 flashcards in 2 minutes?
