I have replaced our kitchen cabinets and now will put in a new sink. The new sink has the drains in different places (farther apart and close to the back wall) than the one we replaced. Can I put a 90 elbow coming directly out of the wall to drain directly into 1 drain, or should I try and accomplish the new plumbing by a T between both drains? Is there a better/worse option?

Go with the Tee, kitchen drains do not like 90 degree bends if you can avoid them.

Is this a double sink? If so the pipes attached to the sink drains should point toward each and be connected with a tee. This tee does not necessiarly have to be in the center between the sinks.The pipe out of the tee should connect to the trap. The trap can be position in any direction to start toward the wall. In other words as you look at it from the front, the trap can be turned sideways to align with the drain. The pipe out of the trap should point toward the wall drain. A 45 degree or 22 1/2 degree ell can be put on wall drain, to look at trap, but a 90 degree should not be required.

I'm with Herald on this. What he's proposing is a continuous waste,(see image). The image I put up is a center outlet but there are others we use that are end outlets. It all depends on where the stub out comes out of the wall. DO NOT install a 90 degree elbo or a horizontal tee on horizontal drain line as they generate clogs. If you have to use a bend use a 45. Good luck, Tom
