20 POINTS!!

Rob is asked to simplify the expression below.

10x – 2(4x + 6y) + 3y

He states that the simplified expression is 2x + 15y because using the Distributive Property yields 10x – 8x + 12y + 3y, and then combining like terms yields 2x + 15y.

Explain the error in Rob's reasoning.

Write the correct simplified expression for 10x – 2(4x + 6y) + 3y.

This is the answer. I did it and got that. You do distributive and then combine like terms.
