You have the following algebraic expression:

-6у - 9х - 1 - 3х - у

in order to simplify the previous expression, order like terms first:

-6у - 9х - 1 - 3х - у =

-6y - y - 9x - 3x - 1

next, simplify like terms:

-6y - y - 9x - 3x - 1 =

-7y - 12x - 1

Hence, the simplified expression is -7y - 12x - 1
