Answer 2

Given: $-9x +( -3x)$

We have to add the above numbers.

As we know that if two negative integers are to be added then an addition operation is performed and the solution obtained has a negative sign.

We are solving in the following way:

We have,

$-9x +( -3x)$

Solving the above expression further we get,

$=>-9x-3x\\=>-12x$

Hence, we get the solution is$-12x$.
