Answer:

Step-by-step explanation:

Look for one or more common factors.  Note here that 5 is a factor of 10x and also a factor of 5y, so 5 is a common factor of 10x+5y, and so ...

10x+5y = 5(2x + 1y) =  5(2x + y)

Repeat:  dividing both terms of 10x+5y by the common factor 5 yields

5(2x + 1y) = 5(2x + y)
