9y-(8-3y)+16 =

5x-(2-4x)+8x-7=

-(-5c-8)+6-9(-8-6)

-5(3y-7)-2(6+4y)+3y

5(3z-7)-9(-8z-6)

-4(3x-6)-3(2+7x)

7x-3(5x+2)-6(7+2x)

Answer 1

9y - (8 - 3y) + 16 = 9y - 8 + 3y + 16 = 12y + 8

 

5x - (2 - 4x) + 8x - 7 = 5x - 2 + 4x + 8x - 7 = 17x - 9

 

-(-5c - 8) + 6 - 9(-8c - 6) = 5c + 8 + 6 + 72c + 54 = 77c + 68

 

-5(3y - 7) - 2(6 + 4y) + 3y = - 15y + 35 - 12 - 8y + 3y = - 20y + 23

 

5(3z - 7) - 9(-8z - 6) = 15z - 35 + 72z + 54 = 87z + 19

 

-4(3x - 6) - 3(2 + 7x) = - 12x + 24 - 6 - 21x = - 33x + 18

 

7x - 3(5x + 2) - 6(7 + 2x) = 7x - 15x - 6 - 42 - 12x = - 20x - 48

Answer 2

9y-(8-3y)+16=9y-8+3y+16=12y+8

5x-(2-4x)+8x-7=5x-2+4x+8x-7=17x-9

-(-5c-8)+6-9(-8-6)=5c+8+6+72+54=5c+140

-5(3y-7)-2(6+4y)+3y=-15y+35-12-8y+3y=-20y+23

5(3z-7)-9(-8z-6)=15z-35+72z+54=87z+19

-4(3x-6)-3(2+7x)=-12x+24-6-21x=-33x+18

7x-3(5x+2)-6(7+2x)=7x-15x-6-42-12x=-20x-48
