The answer is 3. The only common factor between the numbers is 3, because 15 is 3 times 5, while 9 is 3 times 3.
Th answer is 3/4 I’m pretty sure
Simplify the following:
3 x + 2 y + x + 3 y
Grouping like terms, 3 x + 2 y + x + 3 y = (2 y + 3 y) + (3 x + x):
(2 y + 3 y) + (3 x + x)
2 y + 3 y = 5 y:
5 y + (3 x + x)
3 x + x = 4 x:
Answer: 5 y + 4 x
