Very new to repairing bikes. I’ve replaced the tubes on both tires now multiple times. However, a day or so after, the tubes go flat. Am I pinching them or what can I do to fix this? The tires are from 1987 so pretty old.
Yeah those tires were dead 20-30 years ago. Get some new ones.

im also no pro, so beware.
if theres a repeating puncture, the tyres at that age might well be busted.
check the entire inside and outside for signs of cracking or exposed threading. also check the inside of the rim for any sharp bits as well as the nubbins of the spokes for anything that could puncture your tubes.
edit: something about rim tape, but im not there yet

You need new tyres, but also, are these new tubes? both going flat multiple times simultaneously?
Get new tubes with your tyres, and before you install them, check the rims carefully with your bare hands and check for anything sharp, wrap the rim interior with electric tape if you don’t have rim tape.

That looks like a pretty nice vintage bike; Tange #2 was good steel, Shimano 600 was basically Ultegra, the second-best parts group in Shimano’s lineup. Plus the little cutouts in the lugs indicate a well- built bike, and the paint is pretty rad. So yeah, this thing is definitely worth fixing up.
The tubes repeatedly popping would be due to, most likely, something sharp that’s embedded within the tire. You can try to find this by wiping a cloth along the inside of the tire and seeing if it gets snagged in anything.
Also, very important that you make note of *where* the puncture occurred on the tube so you can match it to the same section of tire to narrow down the location of the puncture.
Other potential causes could be a bad rim strip, a spoke that is too long and punching through the rim strip, or using too low tire pressure that can cause a pinch-flat aka snakebite.

replace the tires.
install cloth rim tape of the correct width & diameter onto the rims.
when a tube goes flat you need to be inspected the tire, rim, & old tube for how. have a plastic container of water, pump air into the flat tube, then put it into the water, and see where air bubbled are escaping the tube in the water. is air leaving the tube on the rim side, sidewall, or outside or tire side? then, depending where the air is escaping, you either inspect the tire or the rim. maybe some glass is stuck in the tire. maybe there is too much friction between the rim & tube & it’s causing small punctions.
watch this or other similar video on fixing flats, notice he mentions the importance of inspecthing the tube & determining what fixed the flat. https://m.youtube.com/watch?v=Suh1-o6KBo8
