You distribute first
6d+14=5+6d
then you place the variables on one side and solve for d
14=5
this equation has no solution

Distribute 2(3d+7)=5+6d
Multiply 2 and 3d to get 6d
Multiply 2 and 7 to get 14
6d+14=5+6d
Now subtract 5 from both sides
6d+9=6d
Subtract 6 form both sides
9=0
Your variable has dropped out.
