If -6d = 42 then 6d = -42. then divide by 6, d = -7
-6d = -42-6(7) = -42d = 7
72-6d=6 subtract 72 from both sides -6d=66 divide by -6 d=-11
yes you can
9d-19=6d+2 ... add 19 to both sides and subtract 6d from both sides... 9d-6d=2+19 3d=21 d=21/3 d=7
The pressure test for API 598 is slightly less pressure and less duration than API 6D. API 6D is specifically for pipeline valves.
For most molding, size 6D finishing nails will do the job. This is not universal for all moldings and you may need to try a size 4D for some styles.
6d = c Divide both sides by 6: d = c/d
API 6D exceeds API 598 in both pressure and duration.
3c - 4d = 6d + 4c Subtract 4c from both sides: -c - 4d = 6d Add 4d to both sides: -c = 10d or c = - 10d

2(3d+7)=5+5d. 6d+14=5+5d 6d+9=5d 9=-1d d=-9 I think that's correct. If it is, ur welcome.
