Answer:

8xyz

Step-by-step explanation:

Given:

Add 4xyz + (-3xyz) + (-*-7xyz)

Solution:

Concept: Addition of variables

Treat the terms "xyz" as a group variable and proceed to carry out the addition process as you would for normal set of numericals. You can also take xyz outside and simply carry out the addition process for the numericals and then add it again.

4xyz + (-3xyz) + (--7xyz)

[-*- = +]

The above concept tells us that the multiplication of two negative signs gives us a positive sign, which makes it an addition.

Similar, multiplication of a positive and negative sign makes it a negative sign leading to subtraction.

4xyz - 3xyz + 7xyz       [Follow it stepwise]

xyz + 7xyz                    [Follow it stepwise]

8xyz

Hence, the final answer is 8xyz.

Hope this helps!
