If 2 people have 60 shares of stock between them and you double the number of shares of the 1st person and half the number of shares of the 2nd person so that they both have equal shares. How do find the number of shares the 1st person has?

let second person have x shares
then first person has 60x shares
after doublinghalving .....
second person has x/2
first person has 2(60x)
then
x/2 = 2(60x)
x = 4(60x)
x = 240  4x
5x = 240
x = 48
so the first person has 12 shares and the second has 48
check: (1/2)48 = 2(12)
