Solve the equation for d

0.2(d-6)=0.3d+5-3+0.1d

Work:
1. distribute
2. 0.2d-1.2=0.3d+5-3+0.1d
3. 0.2d=0.4d+3.2
4. -0.2d=3.2
5. divide
6. d= -16
I even did a check
0.2(d-6)=0.3d+5-3+0.1d
0.2(-16-6)=0.3(-16)+5-3+0.1(-16)
0.2(-22)=0.3(-16)+5-3+0.1(-16)
-4.4=-4.4

Is this correct? Thanks for checking my work

1. Correct

2. Thanks because I thought I was correct but my friend got 5 1/3 for the same work
doing0.2d-1.20=.40d+2
+1.2 to each side
then taking 0.40d to each side
getting0.6=3.20
divide each side by0.6 giving her 5 1/3
so where did se go wrong, so I can help her out

3. 0.2d - 0.4d does not equal 0.6

0.2d-1.20=.40d+2

0.2d - 0.4d = 2 + 1.2

-0.2d = 3.2

d = 3.2/-0.2

d = -16
