This is different from other forms. "〜(よ)うぜ" is a strong suggestion to friends. "〜(よ)う" is a simple "Let's do it." But "〜(よ)うじゃないか" is more like saying, "Why don't we do this together?" It tries to get everyone to agree.
Don't use this when you want to say "Let's not do something." For example, you can't say "Let's not go." This grammar pattern is only for saying "Let's do something." To say "Let's not," you need to use different words. You could say "Let's stop doing that." Or you could use a word that means the opposite.
Use this when you want to strongly suggest doing something together. It makes your idea sound good and helps everyone agree. It is like saying, "Let's do this, right?"
