Question

How do you subtract `(9v + 5) - ( 9v + 5)`?

Answer 1

0

Explanation:

Both expressions are the same. If you subtract 4 from 4, the result is zero.

Or you can remove the parentheses and process the arithmetic;
`9v+5 -9v-5=9v-9v+5-5=0`

Answer 2

To subtract `(9v+5)-(9v+5`), we can expand first and then simplify like terms.

Answer: `0`

Explanation:

We are given this expression (`9v+5)-(9v+5)` and we are trying to find an answer to this.

First, we will expand the second bracket which is `-(9v+5)`
Remember the negative in front of the bracket represents `-1`.

Now we multiply `-1` by all the numbers in the bracket, so we multiply `-1` by `9v` which is equal to `-9v` and `-1 xx 5` which is `-5`.

`-(9v+5) = -9v-5`

Now that we have expanded the bracket, we have the expression:

`9v+5-9v-5`

We can put like terms together and simplify as much as we can.

`9v-9v =0, and 5-5 = 0.`

`9v+5-9v-5=0`
