Is 120 > x50 the correct answer to Jack and Jason drove a total of 120 miles to go to the same concert. Jack drove 50 miles less than Jason. How many miles did Jason drive?

Let x = the miles that Jason drove.
x + x  50 = 120
2x = 170
x = 85 
I think I should specify that this is supposed to be written as an expression and not an equation. We are supposed to be translating an expression written by our classmates, and this one really has me confused.
