Alocal hamburger shop sold a combined total of 380 hamburgers and cheeseburgers on wednesday. there were 70 fewer cheeseburgers sold than hamburgers how many hamburgers were sold on wednesday

380 = c + h

c = cheeseburgers

h = hamburgers

c = h - 70

380 = (h - 70) + h

So, fire we are going to add 70 to both sides.

450 = 2h

Divide by 2

225 = h

Hamburgers = 225

Cheese burgers = 225 - 70 = 155

380 = 155 + 225

There were 225 hamburgers sold on Wednesday.
