-7a -19c
12a -30c
21a +11c

26a -38c

Answer:

The correct option is 4.

Step-by-step explanation:

The given expression is

\((-7a-19c)-(-12a+30c)-(-21a-11c)\)

Using distributive property we get

\(-7a-19c-(-12a)-(30c)-(-21a)-(-11c)\)

\(-7a-19c+12a-30c+21a+11c\)

Combine like terms.

\((-7a+12a+21a)+(-19c-30c+11c)\)

On simplification we get

\((26a)+(-38c)\)

\(26a-38c\)

The simplified form of given expression is 26a-38c. Therefore the correct option is 4.
