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
