Question

1-2n) - 7n(12-2) simplify this and show work​

Answer 1

For this case we must simplify the following expression:

`(1-2n) -7n (12-2) =`

We solve the operation of the second parenthesis, taking into account that different signs are subtracted and the sign of the major is placed:

`(1-2n) -7n (10) =`

We multiply:

`(1-2n) -70n =`

We eliminate the parentheses:

`1-2n-70n =`

We add similar terms, taking into account that equal signs are added and the same sign is placed:

`1-72n`

Answer:

The simplified expression is:
`1-72n`
