Question

Which expressions are equivalent to this expression?

y+y+y+3z



Select each correct answer.

3+y+3z
3(y+z)
2y+2z+y+z
3y+z

Answer 1

I think it’s 3 +y+3z because when you add a number to a variable it will automatically become multiplication so in this case it would be 3y which also means 3xY which also is Y three times and then just add the 3z

Answer 2

The correct answers are the second and third ones
