Given:
The pair of composite numbers: 10 and 15
To find:
The greatest common factor (GFC) for the given pair of composite numbers.
Solution:
Two composite number are 10 and 15.
The factor forms of these two numbers are


It is clear that the common factor is 5 in both factor forms. So, the greatest common factor is

Therefore, the greatest common factor of 10 and 15 is 5.
Answer:
What do you mean?
Step-by-step explanation:
8 - 4(x - y) = 2x + 6
8 - 4x + 4y = 2x + 6
-4x - 2x + 4y = 6 - 8
-6x + 4y = -2
6x - 4y = 2 <====
