Question 610500: Bob's Burger Barn sold 495 hamburgers today. The number sold with cheese was 6 less than twice the number sold without cheese. How many hamburgers with cheese were sold and how many without cheese were sold?
This is what I came up with so far : (2w - 6) + c = 495, but still couldn't find the answer.

two unknowns usually means two equations

"sold 495 hamburgers today" ___ c + w = 495

"The number sold with cheese was 6 less than twice the number sold without cheese" ___ c = 2w - 6

substituting ___ (2w - 6) + w = 495

solve for w, then substitute back to find c
