Answer 1

Which expression is equivalent to x + y + x + y + 3(y + 5)? 2x + 5y + 5 2x + y + 30 2x + 5y + 15 2x + 3y + 10


`x + y + x + y + 3(y + 5)= \\ \\ x+y+x+y+3y+15= \boxed{ 2x+5y+15 }`

Answer 2

Option 3 -
`x+y+x+y+3(y + 5)=2x+5y+15`

Explanation:

Given : Expression
`x + y + x + y + 3(y + 5)`

To find : Which expression is equivalent to given expression ?

Solution :

Expression
`x + y + x + y + 3(y + 5)`

Open the bracket,

`x + y + x + y + 3y +15`

Add like terms,

`2x+5y+15`

Therefore,
`x + y + x + y + 3(y + 5)=2x+5y+15`

So, option 3 is correct.
