To do this let's put 129 where X is, like this: -12(129)+14(129)-6(129)

Now we multiply -12 by 129, which is equal to -1548.

Now we multiply 14 by 129, which is equal to 1806.

Now we multiply -6 by 129, which is equal to -774.

Now, let's put these numbers into an equation, like this: -1548+1806-(-774).

The answer to this equation is 1032.

I hope this helps.
