Question

anonymous · Answer

collect your like tersm on each side and then solve for the variable. What do you get when you collect like terms?

anonymous · Answer

22d = 0

anonymous · Answer

right?

anonymous · Answer

Not zero, check your right side. You need to bring the +1 over from the left side, crossing the bridge over the equal sign, forcing it to change signs. You are left with -1-1 which is not zero but -2. No wsolve for the variable.

okay so i done that ... but i dont think -2 can be divided by 22..so is that the answer

anonymous · Answer

You will now have:
$$42d+1=20d$$
$$42d-20d=-1-1$$
$$22d=-2$$
$$d=\frac{ -2 }{ 22 }$$
d=-1/11

If you want you can turn the fraction into a decimal but the fraction is acceptable to leave in its lowest terms. 

Yes, you can distribute the negative sign along with the value as you divide right through.
