Hello and welcome to just answer, Super mechanic here. The first thing you want to do is try to push down on the hood while you have soomeone pull on the cable with the pliers, If that doesn't work then you will have to reach under there with a long screwdriver and try to unlatch it that way.
If all of that fails, then you will have to reach up in there where the latch is and take the bolts out with a small wrench, I would try wiggling the hood back and forth while someone pulls the cable first.
Remember you DO NOT have to accept until you are 100% satisfied with the answer, but, *WE DON'T GET PAID* unless you hit *ACCEPT*
