what's the question ndndn
Answer:
Step-by-step explanation:
Using the two given equations:
x - y = 34
x +y = 212
Rewrite the first one in terms of x:
x = 34 + y
Now replace x in the 2nd equation:
34 + y + y = 212
Simplify:
34 +2y = 212
Subtract 34 from both sides:
2y = 178
Divide both sides by 2:
y = 178/2
y = 89
Now replace y in an equation to solve for x:
x + 89 = 212
x = 212-89
x = 123
He has 123 domestic stamps and 89 foreign stamps.
