Question

Simplify the following expression.
2x − 2y − 5z + 2x + 2y + 3z

4x − 4y − 2z

4x − 4y − 8z

4x − 4y + 8z

4x − 2z

Answer 1

2x-2y-5z+2x+2y+3z

Since 2x and 2x are like terms, add 2x to 2x to get 4x.
4x-2y-5z+2y+3z

Since -2y and 2y are like terms, subtract 2y from -2y to get 0.
4x-5z+3z

Since -5z and 3z are like terms, subtract 3z from -5z to get -2z.
4x-2z
