It is an equation and the value of d is 2
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.

3c - 4d = 6d + 4c Subtract 4c from both sides: -c - 4d = 6d Add 4d to both sides: -c = 10d or c = - 10d
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
If -6d = 42 then 6d = -42. then divide by 6, d = -7
-6d = -42-6(7) = -42d = 7
That is an algebraic equation. If you are asking what the solution is for the above equation, it would be:d = 7
They can be simplified to 10d
72-6d=6 subtract 72 from both sides -6d=66 divide by -6 d=-11
6d = c Divide both sides by 6: d = c/d
9d+3
