Answer:
6x-11y-z
Step-by-step explanation:
*note* Just like in the alphabet, the order of your answer will go x, y, then z.
1. The only numbers with x as a variable is 2x and +4x. You see that 4x has a plus sign in front so you should add 2x and 4x together which equals 6x.
2. The only numbers with y as a variable is -5y and -6y. The way you would write this is -5y (+) -6y. The plus sign doesn't affect the equation at all, so the answer would be -11y.
3. The only numbers with z as a variable is -2z and +(1)z (the 1 is basically invisible lol). You want to add -2z and z, which equals -(1)z, which is -z.
