Let t = the number of tacos sold
Let b = the number of burritos sold
3t + 7.25b = 595
B=2t
They're called variables (this sounds like vary because the number that a letter could represent varies) so when i say 1 + x = 3 it is saying that they don't know the value of x yet but of course you can solve that by subtracting 1 from 3 which is 2
