Answer:
The number of hamburgers sold was 126.
Step-by-step explanation:
Let h = number of hamburgers sold
let c = cheeseburgers sold
c+h = 378
c = 2h
Substitute c =2h into c+h =278
c+h =378
2h+h = 378
Combine like terms
3h = 378
Divide by 3
3h/3 =378/3
h =126
The number of hamburgers sold was 126.

but they need the whole page to answer this question.
Answer:
8x +5
Step-by-step explanation:
The sum is found by combining "like" terms—those that have the same arrangement of variables.
The first expression, 2x +6, has terms 2x and 6.
The second expression, 6x -1, has terms 6x and -1.
In each case, the first term listed is first-degree in the variable x. These are "like" terms, so can be added:
... 2x +6x = (2+6)x = 8x
The second term listed in each case is a constant. These are "like" terms, so can be added:
... 6 + (-1) = 5
Then the sum of the given expressions is the sum of the results from adding like terms:
... 8x + 5
