Question 8271: please help me solve this equation..... 16.5d-(d+3)=(d+2)+7
20.6(x+2)=4-(3-2x)=1 24.2(x+1)+15x=-(3x-17)+5x 28.8y-3(4-2y)=6(y+1)-2 32.-4(2x-5)+3x=x-28 36.-4(2x-5)+3x=x+x-28 40. 7-24-3x+8x=-(x+31)

16.5d-(d+3)=(d+2)+7
5d-d-3=d+9
4d-3=d+9
3d-3=9
3d=12
d=4

20.6(x+2)=4-(3-2x)=1
check to see that you copied the problem accurately...you have two equal signs

24.2(x+1)+15x=-(3x-17)+5x
2x+2+15x=-3x+17+5x
17x+2=2x+17
15x+2=17
15x=15
x=1

28.8y-3(4-2y)=6(y+1)-2
8y-12+6y=6y+6-2
14y-12=6y+4
8y-12=4
8y=16
y=2

32.-4(2x-5)+3x=x-28
-8x+20+3x=x-28
-5x+20=x-28
-6x+20=-28
-6x=-48
x=8

36.-4(2x-5)+3x=x+x-28
-8x+20+3x=2x-28
-5x+20=2x-28
-7x+20=-28
-7x=48
x=
x=6

40. 7-24-3x+8x=-(x+31)
-17+5x=-x-31
-17+6x=-31
6x=14
x=
x=2
x=2
