let the price per share of company X and company Y be X and Y respetively
:
A. Bob's shares:2000X+10000Y=340000....eq 1
Frank's shares:8000X+6000Y=340000...eq 2
:
B lets rewrite eq 1 to 2000X=340000-10000Y
:
now divide by 2000 on each side
:
X=170-5Y
:
substitute X's value into eq 2
:
8000(170-5Y)+6000Y=340000
:
1360000-40000Y+6000Y=340000
:
-34000Y=-1020000
:
dollars per share of company Y
:
dollars per share of companyX
