Parentheses ... there are some, but what's inside is already in simplest form
Exponents ... none
Multiplication ... the -2 is multiplied (distributed) over the (1a + 9)
... 4a + -2a - 18 = 6
Division ... none
Addition ... -2a is added to 4a
... 2a - 18 = 6
Subtraction ... 18 is subtracted from 2a ... unlike terms, so nothing happens
2a - 18 = 6 ... use algebra to solve for a
