Question 362885: Julius sold five times as many computers as sam sold last year. It total, they sold 78 computers. How many computers did julius sell?
I tried:
Julius: 5x
sam : x
total: 78
I can't figure out how to write the equation out. I tried x + 5x = 78 but it didn't seem to work. I am having trouble figuring out how to write the equation.

Let J = Julius

Let S = Sam

J + S = 78
J = 5S

Solving by substitution, I got Julius is 65 and Sam is 13.
