Answer:
Domestic Stamps: 60
Foreign Stamps: 36
Step-by-step explanation:
96 - 24 = 72
72 ÷ 2 = 36
36 + 24 = 60
d - f = 24
60 - 36 = 24
24 = 24
d + f = 96
60 + 36 = 96
96 = 96
Answer: d=60 and f=36
There are 60 domestic stamps and 36 foreign stamps.
Use the elimination method to solve
d-f=24
-d+f=96
_______
Line them up and them subtract
-2f=-72
The d cancel out
Isolate f by dividing both sides by -2
f=36
Replace f with 36 in either equation and then solves
d-(36)=24
Isolate d by adding both sides by 36
d=60
