4/5 y + 7/10 z - 1/5 y + 1/5 z . combine like terms . PLEASE HELP

Answer 1

Answer:

3/5 y   +9/10 z

Step-by-step explanation:

4/5 y + 7/10 z - 1/5 y + 1/5 z

4/5 y - 1/5 y + 7/10 z + 1/5 z

We need to get a common denominator for the z term of 10

4/5 y - 1/5 y + 7/10 z + 1/5 *2/2 z

4/5 y - 1/5 y + 7/10 z + 2/10 z

3/5 y   +9/10 z
