a = -1

Step-by-step explanation:

First, combine like terms. Like terms are terms with the same amount of the same variables.

6a + 5a = -11

(6a + 5a) = -11

(11a) = -11

Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Divide 11 from both sides:

(11a)/11 = (-11)/11

a = -11/11

a = -1

a = -1 is your answer.
