Answer:
The answer is 17x - 4y + 23z
Step-by-step explanation:
Given : To add 2x +5y – 3z ,4x +9y+8z and 11x – 10y +18z
Solution : (2x +5y – 3z) + (4x +9y+8z) + ( 11x – 10y +18z )
Opening the brackets, we get
= 2x +5y – 3z + 4x +9y+8z + 11x – 10y +18z
Rearranging the like terms, we get

= 17x - 4y + 23z
