Please check these simplified expressions(my answer is after the ;)

4(2k-6)-8(3-3k); -16k-(-48)

9+(-2k)+(-4)-6k; -8k+5

-x+4x-(-8x)-9+2x+1; 13x+(-8)

5(-3x+6)+8x; -7x+30

8+6x+4-8x; -2x+12

5(-m-3)+4m-10; -9m+5

  • Pre-Algebra(please check) - ,

    4(2k-6)-8(3-3k); -16k-(-48)
    slow down
    8k - 24 - 24 + 24 k
    = 32 k - 48

    9+(-2k)+(-4)-6k; -8k+5
    yes

    -x+4x-(-8x)-9+2x+1; 13x+(-8)
    yes

    5(-3x+6)+8x; -7x+30
    yes

    8+6x+4-8x; -2x+12
    yes

    5(-m-3)+4m-10; -9m+5
    typo maybe?
    -5m -15 + 4m -10
    = -m - 25
