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.
