Question

Simplify the following.

-
1. 3m - 2n + 5m
2. -b - b + 5
3. 50 - 9 - 8C + 5
-

Answer 1

1.
`8m-2n`
2.
`-2b+5`
3.
`-8c+46`

Explanation:

Given the following questions:


`3m-2n+5m`

`-b-b+5`

`50-9-8c+5`

To simplify the following we are going to have to regroup and combine like terms which means we are going to use inverse of operations on terms with similar variables.

Question one:

`3m-2n+5m`

`3m-2n+5m=3m+5m-2n`

`3m+5m-2n`

`3m+5m=8m`

`=8m-2n`

Question two:

`-b-b+5`

`-b-b=-b+-b=-2b`

`=-2b+5`

Question three:

`50-9-8c+5`

`50-9-8c+5=-8c+50-9+5`

`-8c+50-9+5`

`50-9=41`

`-8c+41+5`

`41+5=46`

`=-8c+46`

Which means your answers are "8m - 2n, -2b + 5, and -8c + 46."

Hope this helps.
