Answer:

-3

Step-by-step explanation:

-4a - 2a - 7 = 11

-6a - 7 = 11                                      Combine coefficients.

      +7   +7

-6a = 18                                           Isolate the variable.

a  = -3                                 Divided by 6 on both sides to isolate the variable.
-3. add 7 to even and combine the like terms to get -6a=18. divide both sides by -6 to get a= -3
