Question

−2(3d − 1) + 4d
Simplify

Answer 1

-2d+2

Answer 2

Distribute the -2 across (3d-1) to make -6d+2 + 4d and then combine the like terms, meaning the -6d and 4d. You should get -2d+2. To understand a little better how to combine like terms, consider having 3 panthers (3p) and 2 panthers (2p) so when you add 3p and 2p you get 5p, similar to how 3 panthers plus 2 panthers is 5 panthers. Simple, yeah?
