Answer:

4x - 3y + 6z.

Step-by-step explanation:

He wrote 62 instead of 6z on the first line.

He made 2 mistakes on the last line:

He didn't subtract the x terms, there was no term = 5.

The -3y + 6z does not simplify to 3yz, the terms have an add process not a multiply.

The correct solution is

5x - x - 3y + 6z

= 4x - 3y + 6z.
