Good luck to you !!

Answer 4

multiply out and combine.

7(2x-4) - ( 10-3x)

14x - 28 - 10 + 3x

17x - 38

.

Answer 5

14x-28-10+3x

17x-38

Answer 6

use the distributive property on the first term:

7*2x - 7*4 - (10-3x)

14x - 28 - (10 - 3X)

now add the additive inverse of what's left in parens, since you're subtracting:

14x - 28 - 10 +3x

combine like terms

14x + 3x - 28 -10

17x -38

done!
