Answer:
6 + 10y
Step-by-step explanation:
Hi,
To begin, you need to distribute the 2 to 3 and 5y (same thing as multiplying it).
2(3 + 5y)
6 + 10y
(Multiply the 2 by 3 and then the 2 by 5y)
Since 6 doesn't have a variable and 10y does, you can't combine them and, therefore, 6 + 10y is your answer.
I hope this helps :)
