    Answer:

    The last lines are the final answers, if you need a deeper explanation let me know but I wanted to make sure you understood and got it in time.

    Step-by-step explanation:

    2(x+4)-3(y+2x)

    2x+8-3y-6x

    -4x-3y+8

    2d+3(4d+2k)-3k

    2d+12d+6k-3k

    14d+3k

    5(4m-2r+7)+4m+3r

    20m-10r+35+4m+3r

    24m-7r+35

    I hope I didn’t get anything wrong in a hurry!
