If I join the Brotherhood and the Minutemen will Nick Valentine survive?

I am close to breaking in to the Institute. I know I will ally with the Minutemen (in the general) no matter what but I joined the Brotherhood of Steel, too. The Brotherhood said when I find a way to break in, go to them immediately. When I got the courser chip decoded, the Railroad said I should go to them first.

I want to help the Brotherhood, but I'm afraid that if I attack the Institute with the Brotherhood, that we will destroy the Railroad and the Institute. The only synth I want to live is Nick.

If I go with the Brotherhood, will they kill Nick in the end?

Solution 1:

Nick survives every ending. He will not be happy if you sided with the institute thou.
