Question

The difference between the number of items on two grocery lists is 7. The combined total number of items on the lists is 33.

Answer 1

Answer:

20 and 13

Step-by-step explanation:

If one list is 'a' and the other one is 'b' then

a-b = 7 and a+b = 33

a-b+a+b = 7+33

2a = 40

a = 20

Now, 20 - b = 7

-b = -13

b = 13
