if this bothers you, review the distributive property and order of operations
−5 + 4(−2x+6)−3x
= -5 + 4(-2x) + 4(6) - 3x
= -5 - 8x + 24 - 3x
Now, since addition is commutative, that's
= -8x - 3x - 5 + 24
= -11x + 19

we are just volunteers who drop by when we have time. There's no guarantee just who or where that will be. Sometimes you need to be patient.
