What is the answer to 6 (1-x) - 5 (3-2z)

You would just distribute.

6 times 1 = 6

6 times - x = - 6x

So that would come together and be 6-6x. You would just do the same for the next one.

-5 times 3 = - 15

-5 times 2z = - 10z

Now, all of that together is 6-6x-15+10z. Finally, you would just combine like terms.

6-15 = - 9

Your answer would be - 9-6x+10z or it could be in a different order, but it's still correct.
