11 more than twice a number has the same value as 8 times the difference of the number and 5

11+2x = 8*(x-5)

11+2x = 8x-40

11+40+2x = 8x-40+40

51+2x-2x=8x-2x

51 = 6x

51/6 = 6x/6

8.5 = x

Therefore, your number is 8.5.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
