Answer:
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.
