Answer:
Otylia's solution is incorrect
Correct solution is 5y
Explanation:
Otylia simplifies the expression 4y + y to 4y^2.
LEts simplify the expression 4y+y and check with Otylia's solution
4y and y are like terms
y or 1y are same
4y and 1y are like terms
To combine like terms, we add only the coefficient of y
So 4y + 1y = 5y
Otylia simplifies the expression 4y + y to 4y^2
4y^2 is not correct. So Otylia's solution is incorrect
