the "2 players" argument fails when you account for the fact that they are sharing the same resources. (e.g bottom lane is splitting them up, top lane is getting all the lane resources for himself)
assuming the game is rightly balanced a top lane and a bottom lane absorbing the same absolute value of gold and XP , a top laner should be equivalent or greater than a bot lane in a 1v2
in summary, support is overtuned, nerf their passive gold gen
First of all, they aren't sharing the same resources. XP? Yes. Gold? No.
Secondly, although they are each receiving half the minion farming XP, they are also getting twice as many kills as a solo laner if they are winning their lane, which means twice as much kill xp to share between them. So the total amount of xp to be gained in the duo lane is greater than "one lane's worth of xp, divided by 2".
This is a good thing. Who would ever play support or ADC if they each only got 50% of the agency a solo laner would? Each player having roughly the same power to determine the course of the game is called balanced design.
Besides that, your math is flawed. You forgot to factor in the hidden teamwork modifier to combat effectiveness. In team games, 50% plus 50% is not 100%. It could be anywhere from 110% to 200% depending on factors like how important teamwork is supposed to be in this game and how well the team players cooperate. If you want to out-duel two players who are each half as strong as you are, you better get a good setup, because you're not up against an equal force. You are up against a superior force. Assuming no advantages to either side, the superior force will most likely win. This is also balanced because the reward is TWO kills, not one. Higher rewards should come with higher risks.
You should absolutely be able to 1v1 either botlaner with a good setup, but you should not be able to 1v2 them both unless you are massively ahead or timed your gank or roam to take advantage of a vulnerable period (like during drake or while they're trying to back with low hp).
