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

Question

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

Answer 1

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
