Question

Simplify the following expression:

3x − 4y + z − 2z + x − y

2x − 6z
4x − 5y − z
4x − 3y − z
4x − 5y − 3z

Answer 1

Answer: 4x-5y-z

Step-by-step explanation: 3x + x -4y-y -2z + z

It becomes a lot easier to simplify if you reorganize the equation so that the same variables are next to each other

Answer 2

4x - 5y - z

Explanation:

3x − 4y + z − 2z + x − y

Add like terms

= 4x - 5y - z
