Offer to try to fix a problem with this phrase:
A: Oh no! We forgot to bring water.
B: Well, I can ride back into town and get some.
A: Dale is going to be really upset when he hears about this.
B: I can talk to him. I'm usually pretty good at calming him down.
"I can..." sounds friendly and helpful.
You can also say "I could..." if your suggestion is a little strange, creative, or unlikely to work:
I could call my friend who works at IBM and see if they have any job openings there.
