In your question you wrote that those who chose pasta were 20 more than chose pasta so I'll assume you meant "than chose hamburgers" ... That said, if you let salad = X then ha. burgers = 6x and pasta = 6x + 20

If we add them together we will get the total orders of 280, so our equation is

x + 6x + (6x + 20) = 280

13x + 20 = 280

13x = 260

x = 20

Remember x = salad so 20 people ordered salad

just for your info ...

hamburgers would be 6x or 6 * 20 = 120 and

pasta would be 6x + 20 or 6*20 + 20 = 140
